红蓝3d成像原理
红蓝3D成像原理人类是通过左眼和右眼所看到的物体的细微差异来获得立体感的,要从一幅平面的图像中获得立体感,那么这幅平面的图像中就必须包含具有一定视差的两幅图像的信息,再通过适当的方法和工具分别传送到我们的左右眼睛。
图像中的任何一个象素的颜色都可以由一组RGB值来记录和表达,图像上所有的颜色,都是由这些红绿蓝三种色按照不同的比例混合而成,这红色绿色蓝色又称为三原色,三原色中任何一色都不能用其余两种色彩合成。
RGB的所谓“多少”就是指亮度,通常情况下,RGB 各有256级亮度,用数字从0、1、2...直到255来表示。
按照计算,256级的RGB色彩总共能组合出约1678万种色彩,即256×256×256=16777216。
通常简称为24位色。
纯黑的RGB值0,0,0;纯白的RGB 值是255,255,255;纯红的RGB值是255,0,0。
纯绿的RGB值是0,255,0;纯蓝的RGB值是0,0,255。
纯黄的RGB数值是255,255,0,可以看出:纯黄色=纯红色+纯绿色,根据互补色原理,补色指完全不含另一种颜色,红和绿混合成黄色,因为完全不含蓝色,所以黄色就是蓝色的补色。
我们可以通过计算来确定任意一个颜色的互补色:首先取得这个颜色的RGB数值,再用255分别减去现有的RGB值即可。
比如黄色的RGB值是255,255,0,那么通过计算:r(255-255),g(255-255),b(255-0),互补色为:0,0,255。
正是蓝色。
红色的互补色为青色,红色的RGB值是(0--255),0,0;而青色的RGB值是0,(0--255),(0--255),由于它们不含有对方的颜色,利用这个特点,用红色来保存一幅图像的信息,而用青色来保存另一幅图像的信息,这样就完全可以用一幅图像来包含两幅图像的信息了。
我们可以用一个公式来表达;第一幅图像RGB1=R1,G1,B1;第二幅图像RGB2=R2,G2,B2,合成后的立体图像RGB12=R1,G2,B2或RGB21=R2,G1,B1。

精彩实例:用Fireworks绘制三维矢量透视图发布日期: 2006-2-6 11:00:54 作者: feng4ever 字体:【大中小】【打印本页】娱乐/搞笑/体育视频免费看!彩信/短信开发平台免费测试您的IT潜质!美萍洗浴、餐饮管理系统 自己开始学习C4D了,可能会放弃使用Fireworks(以下简称FW)制作3D图形了,所以画个画留做纪念,选用了最经典的IPOD MINI 。
为了方便大家查看,给出下图: 1.打底稿,和再纸上画3D图形一样,画一个立体的盒子,想象一个IPOD刚好装进去只要这里透视准确最后的图形绝对不会出现透视的错误,这里推荐使用3D Primitives。
或者可以使用FW自带的“透视辅助线条”,高手的话凭借感觉就好了(透视要点,所有3D图形的平行线条都会在同一点相交..比如立方体的四条竖直的边肯定会在同一点相交)。
2.然后我们画好可见的三个面的平面图,(三视图)这里我们把3D 盒子的各个面"铺在"画布上画,大小比例严格按照尺寸: 3.画完以后,将平面图贴到3D物体上去。
注意按轮廓变形。
4.同上,对准确点,把打开的立体图形的面和原来的那个面仔细的重合,这样这个面上的东西就贴上去了: 5.做一些小修改,使得按钮有立体感,如果仅仅只是把一张纸贴到墙上怎么也不会有立体感的(就象CS里面的窗户,哪个角度看都没有窗沿,因为那只是一张图): 6.正面也贴上去: 7.右边没有内容,不需要贴了,但是这里还要把下面也贴上去,因为我们要制作它的轮廓: 8.如下画出一个四边形: 9.然后把这个四边形连同上面,下面 三个矢量组合,组合形成的矢量就是整个IPOD再我们视野的大小了,换句画说 如果你的IPOD不是透明的,我们不能看到这个形状背后的内容,所以我们给他一个边框,填充为白色: 10.背面同样.... 如果需要换角度的画 可以再很大程度上减少工作量,至少平面的内容不需要更改了。

CENTER NEWS Published by1928 NW Lovejoy Street, Portland, OR 972093D Center Excites NSA VisitorsRare Nazi Book & Stereoscopic Images DonatedI n April 1939 Nazi Germany introduced the “Model Company Act.” Some 100small and large companies were chosen to act as role models for society and otherindustrial and commercial concerns to advance the cause of the National Socialist (Nazi) party.The stereo photographs pictured here, are some of the 212 included in a book titled “DieNationalsozialistischen Musterbetriebe – 1939” (The Nazi Model Company of 1939). Cleverlydesigned indentations in the front and back covers provides storage for a stereoscopic viewerand the images. The book was published by“Raumbild – Verlag” in Munich, that laterpublished other famous stereographic workdocumenting the war.The text is in German and the stereophotographs depict examples of wellorganized companies. In addition toproduction facilities and offi ces, there is astrong emphasis on the recreational facilitiesor company restaurants associated withthese concerns – all intentionally chosen toshowcase the effi ciency, productivity and comfort of life inthose environments.The book, whose estimated value is over $1,500 wasdonated by a supporter in California. It has already resulted inserious thoughts about how to best preserve and display rare andvaluable items. Using a UV meter, Claire Dean, a CSC memberwho is a conservator by profession,measured the ultra violet light levelsof the various cabinets and open areasin the Center. UV light is one of thegreatest hazards to preserving images,manuscripts, and some objects.She found that the display cabinetshave unacceptable UV levels. Theinstallation of fi lters will remedy thisand should not affect the viewabilityof the items.NSA attendees fl ocked to the Center to see for themselves what was happening. They explored theCenter, bought gift store items and left donations. Seen here, NSA President Mary Ann Sell chatswith John Dennis (to her right), Wolfgang Sell (in black) and David Starkman (red shirt).Coming all the way from Japan, CSC member Takashi Sekitani (right) and his friends pose in frontof the Center.During the NSA convention held in Portland in July, eager visitors found theirway to the 3D Center. Not content to donate money, most bought items from the giftstore and some donated items for the Center’s collections. The Center received gifts ofbooks for the reference library, a camera for the display cases, a View Master 65 yearcommemorative viewer and reels from Fisher-Price, a lenticular of Campbell’s Tomato Soup,a large display rack for the Amazing Cards, adisplay of phantograms, a medium format slideviewer which looks like something from the SpaceAge and houses gorgeous 3D images, a beautifulset of 3D conversions and a mirror viewer. Theenthusiasm was universal and spanned severalcontinents, many countries.The night before the NSA Convention opened, the Center’s featured artist,Ray Zone, greeted visitors at a special artist’s recepetion. Photos: John DennisTuesday before the convention began, an artist reception for Ray Zone was anoverwhelming success. As I drove him to the Center, Ray said, a bit nervously, “I hopesome people will come. It’s really awful to do an artists reception and have no onecome.” “Oh, they’ll come,” I replied confi dently. (But I wasn’t so confi dent in reality.Tuesday was not a regular open night for the Center. Most of the people coming to theconvention were just fl ying in and I wasn’t sure they would fi gure out a way to get fromJantzen Beach to Lovejoy. I was hoping at least a couple of car loadsmight come and maybe some of the CSC members.) Were we in for asurprise! When we got to the Center, people were waiting, and therewere so many people there within an hour that they were spilling outonto the street. Ray was surrounded with people curious about his workand his career. He had a great time. Dave Qualman kept opening bottlesof wine and Judith was running to get dip. I glanced nervously towardthe front desk, but there was no need to worry, Obie was entrenchedthere selling everything in sight to eager buyers. Everyone thought theevening was a great success, even the rather weird guy who came upto me and said, “Dude, this is too cool. Who is this Ray Zone dude?”“He’s over there,” I answered, “would you like me to introduce you?”“Far out, this stuff is out of sight.” I took him to Ray (losing him twiceas he veered off to shake hands with other people he imagined were RayZone), then I stood back and smiled as I watched Ray, gracious as ever,chat with the fellow.The 3-D Viewerscope was donated tothe Center by Inovatv Global Parts. Itnow sits in the front window on a timer sopassers-by can see 3D. Photo: Shab LevyJim Harp fi nds anaglyphs to be ideal for restoring and dis-playing stereocards from the late 19th and early 20th century.Many of these old cards are contact prints from glassnegatives and contain an astounding amount of detail. His large anaglyph prints, many of which will be displayed at the Center,allow the viewer to explore subtleties in these classic images that might otherwise remain unnoticed.Harp resides in New Jersey and is an electronic music designer specializing in systems for Broadway shows. His recent focus is “virtual orchestras,” interactive software-based instruments.Special thanks to all who continue to contribute to make the3D Center a reality. Center News is mailed quarterly to thosewho have made a fi nancial contribution of at least $100 in the past year, have staffed one shift or more during the past quarter, or havebeen featured artists or stereo theatre presenters during the past year. This is our second issue. Center News will help keep you advised of the Center’s events and will be the vehicle used to share the worries, needs, and victories of the Center with those who are so committed to its success.This in mind, Center News will not always be “good” news. Sometimes there will be problems or worries to share and Center News will call out to you forhelp. We look forward to hearing your ideas and having your participation.Entering our third quarter of operation, the news is good. The featured art and displays have been amazing. Gifts of items, big and small, have helpedto make the Center interesting. We have built a reasonable amount of inventory for our gift shop and Center visitors enjoy buying items to remember their visit here. Local supporters have been generous in volunteering time to keep the Center staffed and running smoothly even during the NSAconvention. Donations from the stereo communityhave helped pay the lease, stock the gift store andimprove the space.Right now our greatest challenge is to publicize the Center locally. Visitors to the Center are impressed. Some are positively “wowed.” However, most local people do not know about the Center yet. Many of our visitors have found us justby accident – they were passing by. On some days, attendance is very low. For this reason, the Board of Directors has declared advertising a priority and has passed a one year advertising budget to help increase the numbers of visitors. More visitors will meanincreased donations at the door and gift shop sales. Extending the Cornerstoner membership period by one month was the second matter decided by the Board which affects Center supporters. Originally the Charter period was to end Dec. 31, 2004. An emailed suggestion from a Cornerstoner led to the Board extending the period until Jan. 31, 2005. The extra month allows donorsto spread the tax benefi ts over another tax year. On January 31, the positioning of each Cornerstoner will be determined based on his/her total contribution through Jan. 31, 2005. Only those whose fi nancialcontribution during these fi rst challenging 15 months made this dream possible will be memorialized on the Cornerstoner plaques. In future years many will contribute to the Center because of their love of 3D imagery, their love of photography, because they are interested in the science that enables us to see a fl at object in 3D, or just because they think this unusual and interesting Center should be preserved and allowed to fl ourish. Their contribution will be acknowledged during the year it is made, but no new names will be added to the Charter Cornerstoner group. It is our way of rewarding your faith in this project and your willingness to “put your money where your heart is!”Diamond Donated $5,000 + Mark Gehlar Platinum Donated $2,000 to 4,999Shab Levy Dave QualmanJohn & Dace Roll Diane E.

The intern will work for 10 – 12 hours helping build the Portland area’s awareness of the 3D Center. This will be accomplished through advertising, promotions, and news releases. In order to becomemore familiar with the Center and the art displayed there, the intern will work one shift a week at the Center. Depending on the intern’s interests, he/she may also work to streamline the inventory and product promotion at the Center, help coordinate volunteer help, or work as a liaison for the Center, networking with the communityand other organizations.Fall term begins at Portland State near the end of September. It is hoped that an intern will be located by the fi rst part of October. The selected student will receive school credit for the work done and will receive a stipend from CSC at the end of the term.Ways to Help• Remember the Center gift store for your holiday shopping. • Watch the Center website for the online gift shop.• Work at least one shift a month. It is fun and it keeps us open • Give a friend, relative, fellow worker or someone from your church group a Center brochure. Word of mouth is our best advertising.If you can help with other Center activities, please contact Diane, dianer@ ExhibitorExhibitorJim HarpEtudes in Red and Cyan Nov 4 - Dec 26。

If you have ever wondered what it is like to be a self published photographer, wait a month till he’s not so frazzled, then ask Greg Marshall. Greg has been working on the images, thetext, the layout, chosing a printer, and fi ne tuning the fi nal production of his fi rst book, The Classic Nude in 3D . Classic Nude was published the end of December 2004 and the fi rst sales are in progress. The 3DCenter gift shop and online store will be selling the book. Orders have already come from Japan and several U.S. states.As if this does not keep him busy enough, Greg is the featured artist at the Center in January and February. He has mounted 12 stereo pairs from his classic nude collection for the exhibition. On January 6 (First Thursday), the Center will host a public artist reception for Greg from 6 - 9pm.Marshall has been an active amateur photographer for more than 35 years while making a living as an electrical engineer. He began making stereoscopic images about 10 years ago. He studied graphic arts in high school over the protests of the head of the mathematicsCooperative, which he co-founded in 2000, and is a board member of the Cascade Stereoscopic Club of Portland. He has exhibited in numerous community art shows in California and Oregon and hopes to expand his photographic activity upon retirement.Greg’s wife is also a visual artist, working in watercolor and mixed media. They have two grown children. A large portion of their Canby home is devoted to studio space. You can see more of his work on his website: /gbmarshallCENTERNEWSPublished by 1928 NW Lovejoy Street, Portland, OR 97209Man’s Best Friend, Santa and the 3D CenterThe Classic Nude in 3D :An Exhibit and a BookArtist’s Statement by Greg MarshallMy photographic journey began at age fourteen when my oldest brother (who was my role model) started taking pictures and built a darkroom in our home. My interest was reinvigorated twelve years ago when it became practical to “process” images on a computer. Although I love the artistic and technical aspects of fi ne print making, the dark, smelly environment of the traditional darkroom never appealed to me. So now I work entirely with digital images using a digital SLR camera, archival inkjet printer, and fi lm recorder.My mother tells me that as a small child I was the favorite of all the ladies in the neighborhood because of my easy-going, friendly nature. I’m sure I’ve changed since then, but perhaps that was the beginning of a life in which women have always played an important role; from my mother, who was totally devoted to her children; to my sisters, who taught me about music and many other things; my wife, who brought out the artist in me; and my daughter, who continues to keep me young at heart. So for the past year I have turned my attention away from my usual photography of still lifes to work on a series of images that would portray strength, courage, passion and beauty of woman. Stereo photography is both a challenge and an asset in this endeavor, but I hope you’ll agree that the images selected for this show demonstrate a three-dimensional aesthetic that goes beyond the simple sense of realism that is the power of most stereo photographs.You may notice that some of my images resemble those of Ruth Bernhard, one of my favorite photographers, including one specifi cally crediting her, “Homage to Ruth.” Her work shows a great talent for two-dimensional design and was my inspiration for the idea of abstract design in three-dimensional space.department because the class schedule confl icted with the top math class. In college he took photography and other art courses while majoring in communications, and later earned a Master of Science degree in computer science.His career as an electrical engineer spans more than 25 years. He has worked primarily with various types of imaging systems, including computer graphics, video, medical imaging, and printing systems.Born and raised in Vermont, Greg’s career took him to California, where he was a co-founder in several high-tech companies, and fi nally, to Oregon. He has been active in several photography clubs, including the AfterLight Photo The Center’s fi rst 8 week beginner’s class in stereo photography netted four students, Claire Dean, Jim McMahon, Lisa Metzger, and Colin Johnson. Lisa and Colin were non CSC members and totally new to 3D. The result was two new local members, a great program at the Novem-ber CSC meeting where they showed cards and slides they had created, and a new editor for Stereo Views (Colin). So, do you think we are going to do it again? You bet!! See the sched-ule of upcoming classes on page 2 or check the website for more information. Photo: Shab LevyTed Welker had the Santa Claus suit and the Ho, Ho, Ho, and we had the Amazing Human in 3D system from the Netherlands – it was a natural. There wasn’t much time to advertise, but we got an ad in the Oregonian and one in Willamette Week. On Sunday, December 12, anyone could come to the 3D Center and have their picture taken with Santa Claus in 3D. Several people took us up on the offer. Elwood and Jackie pictured to the right brought their dogs, Ted-e, Chris, Darwin, Hal and Jack to create a family portrait with Santa.The images were put into a collapsible viewer with lenses which could be mailed in a regular envelope or saved as a souvenir. One picture and viewer was $5 and you could get a second image and viewer for $3 more. What a deal! People loved it and next year we will start earlier and promote it more. On our one day of Santa in 3D, we sold $93 worth of pictures and the volunteers had a great time.Fieldtrips, Classes and WorkshopsIn September 2004, the Center offered the fi rst 8 week beginning stereo photography course. The course, taught be Shab Levy, was advertised in Willamette Week. The result was an enrollment of 4 people, two of whom had no exposure to 3D photography and two of whom were CSC members hoping to take more stereo images and to get better results with tips learned in the class. During the November CSC meeting, the students displayed stereocards and slides that they made during the 8 week course. It was impressive.The Center also hosts groups by special arrangement. The charge for a special opening is $50. We have had several student groups and one photography club. Groups of students have been divided in two with the fi rst half taken to the stereo theatre and the second half shown the displays, featured artist, gift shop and other exhibits. The groups then reverse. At the end of their visit thestudents are gathered together and given a talk about how stereo photography works, the various means of viewing 3D, and how one can begin creating 3D images with a simple camera. During the fall we had 2 student groups. Twenty-two students from the TAG (Talented and Gifted) program in Lake Oswego toured the Center in November. They were middle school students and they had great questions and a lot of enthusiasm for the things they saw. They especially enjoyed the slide show, Art in Depth .In the coming year, we will encourage more special groups, classes and workshops.Second year goals for the Center will be largely dictated by what slipped through the cracks the fi rst year. With noidea how challenging it would be to start a business from scratch, we embarked on this project last year with a great deal of enthusiasm, some skills that each of us brought to the venture, lots of ideas, andonly a dim grasp of the details. My grandmother used to say, “The Devil is in the details.” One example is the gift shop. In order to get items wholesale we needed to buy them in some quantity, then break them down into smaller units so we could mark them up to retail price and make some money on them. Because we wanted to encourage beginners, I took boxes of RBT mounts (50 in a box) and broke them into units of 18 mounts (enough for one roll of fi lm). This meant counting, packing in baggies, designing a label to staple on the top, pricing, etc. So it was with QVu mounts, and other small items. Designing and printing signage and labels became a major time drain. Of course we also had to fi nd the items we wanted to sell and we needed to fi nd them from the wholesalers, not the people who were selling them for the same prices we wanted to sell them for. Unlike last year, this year we begin with a stocked gift store, a list of sources for products, some packaging and signage.Establishing systems was another drain on time. We developed protocol for volunteers, exhibiting artists, inventory, accounting for money coming inand going out, fundraisers, brochures (design and distribution), and dealing with advertising and promotion. While there is plenty of room for improvement, we have done a fairly good job setting up a structure.Remembering that we started from an ugly empty space, the accomplishments of the past year are remarkable. The support in the form of donations,exhibits and time have made this possible. Last month the new phone books came out and for the fi rst time the 3D Center of Art and Photography is listed under museums. The Portland Oregon Visitors Bureau’s book of things to do and see in Portland came out in October and for the fi rst time, we were listed. If you search the web for 3D Center of Art and Photography you will fi nd us listed in some interesting places. Despite the fact that we could never fi nd the time to promotespecial openings, we have had fi ve groups arrange fi eldtripsto the Center, four student events and one fl at camera club. Next year we need to develop a promo package for Portland/Vancouver area middle school and high school students and for retirement communities to encourage more group outings.Expanding the number of CSC-sponsored products offered in the gift store and online will increasethe revenue fl ow for the Center, will encourage ideas and experimentation among amateur stereo photographers andwill make the Center unique in its offerings. Of course some well established 3D products simply must be available, but the combination of the expected and unexpected can bevery compelling to both the new and veteran visitor. Greg Marshall’s new book is an example. I like to think that the availability of the 3D Center for marketing and promoting such a book was a factor in Greg’s decision to launch into creatinghis fi rst book. It will be fun to see who else might decide togive a new idea a try.Occasionally during the past year I mentioned variousplans for stabilizing staff. None of these have worked out and part of it has been lack of time to seriously pursue them. We were unable to get an intern from one of the local colleges and I had no time to write any grant proposalsthis year. We will need to devote some energy to resolving this issue for two reasons. First, we need some consistency in the staffi ng. We need someone who is there each day and can update the volunteers and keep track of day to day operations. I am working full time and cannot be that person. Secondly, we need to expand our public hours and can only do this with a staff person - probably paid. A staff person who would work 20hours a week would allow us to expand our hours and maintain the same number of volunteer hours we are currently staffi ng. Each shift would be one volunteer and the staff person. This will take serious consideration of budget, fundraising, and perhaps a grant. We have accomplished a great deal, but there is more to do and the fl ood of support indicates that many hopewe will succeed.Message from theDirector2nd Season’s Beginning LineupGoldDonated $500 to $1,999Dave Allen OR Anonymous CA Gordon Battaile ORRich & Susan Dubnow OR Clarence & Norma Eid ORRon & Pauline Frederickson CA Ron & Jeanne Kriesel OR Greg Marshall OR Martha A.

We did not know what sort of fi -nancial support we would receive from CSC members and the Stereo community at large. We tried to es-timate costs, but many things were only guesses. Having no track record we did not know if the gift store would be profi table, if people would donate at the door, if we could sustain our open hours with volunteers and how much advertising we might need. The goal chart to the left is correct in the amounts received, but the goal itself was pulled from thin air. Early this spring, the CSC Board will be taking a hard look at costs and income from our fi rst year of operation and will develop a budget based on some real experience.January 31, 2005By Diane RulienThe Classic Nude in 3D by Greg Marshall (see front page story)Unseen Ellis Island: Island of Hope, Island of Tears by Sheldon Aronow-itz and Gary Schacker will be showing every hour in the stereo theatre.World of Phantaglyphs by Owen Western is a wonderful collection of largeimages that pop up off the table to surprize and delight Center visi-tors.

I would have been disappointed for the 3D Center’s loss, but I would have been delighted for stereographers and I would have applauded the decision to place the collection in a facility such as these. I do not know of any such offers; however, I do know of two other offers which would have left the collection intact. The 3D Center offered to take the full collection on loan from theNSA and house it, store portions of the collection and rotate other portions through the Center display cases and public areas. The Center would continue to offer research capability for those interested in using the materials, articles and images from the collection. The collection would continue to be owned by the NSA, with the NSA contributing $1000 a year to itsmaintenance, storage, and display. The advantages are obvious. The NSA would receive great press among the stereoscopicworld and in general news releases to the public. A permanent thank you notice would be posted at the Center reminding visitors that the NSA had placed this valuable collection on loan at the Center. NSA would also receive recognition as aFriend of the Center at the $1000 a year level and a link to theNSA website. The 3D Center would get great press for having the collection, would be helped by the $1000 a year which could be used for better display cases, inventory, and cataloging of the Library articles and information. However this offer was declined. Perhaps correctly the NSA Board did not want to own the Holmes Library collection any longer or take on the responsibility for seeing that it was appropriately housed and preserved.The second offer was also made by the 3D Center. The Center offered to pay all costs of moving the collection to Portland if NSA would gift the Holmes collection to the Center. This would cost NSA nothing, would preserve the collection intact, would help the 3D Center in terms of publicity and prestige, and would be a wonderful solution to the preservation of the history of stereography. This offer was also declined. Instead the NSA Board has decided to sell much of the collection on eBay and at NSA conventions to private collectors. A couple of nice pieces will be given to other museums not specifi cally dedicated to stereoscopy, and the papers and more contemporary images will be boxed up and sent to the 3D Center at the expense of the Center. A major part of the mission statement of the Center includes research and history and we are glad to be able to step up and take this heritage. But it is a bittersweet gift when one thinks about what a loss it is for stereoscopy that the Holmes collection is being dismantled and much of it sold off when it could have been kept intact at no cost to NSA. I suspect this is what the donors intendedwhen they made their gifts to the Holmes Library.The 3D communityis facing a terrible loss. In a decision announced last month, the Board of the National StereoscopicAssociation (NSA) has decided to liquidate the Oliver Wendell Holmes Stereoscopic Research Library. Although the decision to “get out of the museum business” may be a wise one for the NSA, a nonprofi t group of nearly 4,000 members dedicated to the promotion and preservation of 3D photography, the dismantling of this valuable resource for stereographers is a tragedy. With no central headquarters and with national conventions moving from one part of the country to another each year, it was diffi cult for NSA to run and promote the Library.The Oliver Wendell Holmes Stereoscopic Research Library was a by-product of a total vision for stereoscopic history and research - formulated and developed by the founders of the NSA. Established on February 20, 1979 the collection was later moved twice, fi nally to Cincinnati, Ohio. The library had no public hours, but was open by appointment with Wolfgang and Mary Ann Sell serving as library curators for many years. Operating solely on donations, the library was an invaluable reference tool to many students and researchers including PBS who used many of the library’s images when producing their award winning series on the Civil War.Although the library operated primarily as a research facility, there were future plans including expanding its services to include periodic projections of 3D slides as well as demonstrations and workshops on stereo techniques. It was hoped that as the library expanded, it would present the many facets of stereo photography to researchersand others interested in this medium. An Internet site was created to give instant access to information within the library including many of its stereoscopic images. To call it a library is perhaps limiting. The Library was stocked with donated items from stereographers who wanted to preserve the legacy of stereo imagery and to establish a space dedicatedto the history of stereoscopy. There were more than 20,000 vintage stereo views housed in the library as well as several thousand modern 3D color slides. There were more than 400 books and several hundred articles in the library’s collection making it the largest assortment of 3D information compiled within one place anywhere in the world. The largest holding within the library was the Helen Dupre Moseley Collection that was gifted to the library in 1985. Consisting of over 14,000 views, this contribution elevated the library to a major repository of not just books on the subject of stereoscopy but ownership of an image collection which provides researchers with an opportunity to study a great variety of historical photographs.Although vintage stereo views comprised the base of the library’s inventory, other forms of 3D such as anaglyph posters and comic books, lenticular images, holograms and View Master reels were also represented in the library’s collection. The library served as a lending source for donated slide programs and works with stereo clubs throughout the country in this regard.Many have never heard of the Library or are unaware of what it held. There were fewvisitors and little publicity about the Library or its contents. If there had been no place to move this collection, one could understand the decision of the NSA Board.

The noted botanist, amateur zoologist, and photographer, had been making a series of images of a young girl named Regina Crosswell. Regina’s twin sister, Lydia, had died in the winter, though the circumstances were unclear. Dr. Addison, however, had become convinced that Lydia had not entirely departed from our earthly plane. Peruse the photographs Addison made and draw your own conclusions.”Combining a love of stereo photography with an appreciation for the beauty of a landscapes, Ron Kriesel has produced an impressive num-ber of breathtaking stereoscopic landscapes over more than 20 years as a stereographer. These large side by side stereo prints are a visual treat, especially when viewed with David Lee large format mirrored viewers.Stereo Theatre: Simon Bell’sLos Caros Viejos: Classic American Cars in CubaIn the Gallery: Amazing StereoJetsby Jim GaspariniSimon Bell’s passion for photography began when he was given a “box-brownie” camera at six years of age. That early interest developed into career inphotography, multimedia and 3D imagery that continues today.While in Cuba, Bell was fascinated by the vast numbers of classic American cars he saw on the streets. Locked in by the American embargo on trade with Cuba established in the 1960s after Fidel Castro took power, and the inability of Cuban citizens to replace older American cars with new ones, the American cars in Cuba were maintained and valued. With his ever present eye for beauty and the unusual, Bell started taking stereo images of the cars and the people. The result was a stereo slide show which won 3rd place at the NSA convention in 2004. The images of cars and people on the streets of Cuba are accompanied by native Cuban music. It is like being transported to another part of the world.First Thursday opens new exhibition with artist’s recep-tion for Jim Gasparini seen here greeting guests, answering questionsand enjoying a glass of wine. Gasparini, who lives in the Bay area, flew to Portland to help set up his show of 20 backlit stereojets, Amaz-ing StereoJets, the first such exhibition held at the Center. Gasparini’s stereojets in-cluded images from Burning Man (see When She Beckons shown as a stereo pair below), scenic lo-cations and a hippopotamus in a tank (a favorite amongvisitors). The images were a sensation for first time visitors as well as veteran stereographers. The experience was enhanced by Gasparini being available to answer questions about the locations and the process of making stereojets.Besides enjoying a glass of wine and light refreshments, visi-tors watched Simon Bell’s award winning slide show, Caros Viejos.Fundraising: the Never Ending Work of a Non-Profit MuseumDoes it seem like we are always fundraising? We are. The Portland Symphony, established more than 40 years ago, recently published that they receive less than 50% of their operating budget from ticket sales. This is not an uncommon statistic for non-profit symphonies, ballets, museums, art galleries, and theatres. The 3D Center is no exception. In 2004, our first year, 90% of our funding came from individual donations of 3D enthusiasts all over the U.S. The other 10 % came from admissions and gift shop sales. In 2005, we dramatically increased the number of visitors. Consequently, the amount of income from admissions and gift shop sales increased from 10% to 25% of our funding. Our costs also rose in 2005 as we hired a part-time employee.In an effort to expand our financial base, theCenter has submitted more than 37 grant proposals to foundations and businessessince December. The competition for this type of funding is fierce and weare just learning the ropes. Some have already sent usrejection letters; others are still considering our proposals. We received a $1000 grant from the Oregon Arts Commission last month and we got our first Corporate Friend membership from MacNaughton, Inc. Check our webpage under Friends for a link to their website. This month mailings for Friends renewals and solicitations for new Friends memberships will be mailed. Please support the Center with as generous a giftas you can. Each mailing you get is prepared, stuffed, addressed and mailed by volunteers because we need your support this year.D o l l a r s I n c o m e 2005D o l l a r sE x p e n d i t u r e s 2005New Acquisition Our thanks to John Little forhis donation of a dual stereo microscope, four eyepieces andRealist stereo camera.

2.5 LWF线形工作流
LWF线性工作流的宗旨是 “所见即所得”。从软件端来说,传统效果图渲染模式和LWF渲 染模式的本质区别是Gamma值 :在传统的效果图制作流程中,使用Gamma1.0表述整个颜色空间 的色阶:在LWF线性工作流程中,会使用Gamma2.2来表 述计算结果颜色空间的色阶。图2-54和 图2-55所示分别是传统渲染模式和LWF渲染模式的效果,如果从效果图布光来看 ,前者必须通过 “补光”才能得到完美的光照效果

and Static3D Plotting for Ordination and ClusteringDescriptionThe vegan3d package provides3D plotting for all vegan ordination methods or any other ordination method that vegan scores function can handle.It can also display hclust results in3D over a 2D plane.Dynamic3D plots are based on the rgl package and static plots are drawn with the scatterplot3d package.Index of help topics:ordiplot3d

Perspective Plot of Renyi DiversityAccumulationvegan3d-package Dynamic and Static3D Plotting for Ordinationand ClusteringDrawing with rgl FunctionsThe rgl graphics are dynamic3D plots that can be spinned and zoomed by mouse.The vegan3d package provides interface to ordination and clustering objects.The functions use rgl setting and conventions and do not change the user settings.For general configuration of the plots,users should check rgl documentation.For instance,general look and feel of drawn items can be configured with material3d.The rgl package may not be available in all platforms,and therefore the package is not automatically attached.If you want to use rgl functions,you must either prefix commands with rgl::or call library(rgl)in your session.Function ordirgl is simalar as ordiplot in vegan,and any ordination result can be drawn with similar conventions.Functions with orgl prefix add items to existing plots,for instance,orglellipse is analogous to ordiellipse.Function ordirgltree draws an hclust dendrogram over a plane.It was originally developed for 2D ordination planes,but any other plane can be used,for instance a projected map.Functions rgl.isomap and rgl.renyiaccum provide alternative dynamic3D plots for vegan isomap and renyiaccum functions.Drawing with scatterplot3d FunctionsThe scatterplot3d package draws static3D graphics,and vegan3d provides an interface for ordi-nation and clustering objects.You must consult the scatterplot3d documentation for configuring your plots.Function ordiplot3d is similar to ordirgl or ordiplot and draws a static3D plot in the standard graphical device.It returns invisibly a plotting object which contains the projected points,andvegan ordi*prefix functions can use this object.For instance,ordiellipse will add ellipses on the projected points.Function orditree3d will draw an hclust dendrogram over a plane similarly as ordirgltree. ordiplot3d Three-Dimensional Ordination GraphicsDescriptionFunction ordiplot3d displays three-dimensional ordination graphics using scatterplot3d.Func-tion works with all ordination results form vegan and all ordination results known by scores func-tion.Usageordiplot3d(object,display="sites",choices=1:3,col="black", ax.col="red",arr.len=0.1,arr.col="blue",envfit,xlab,ylab,zlab,...)Argumentsobject An ordination result or any object known by scores.display Display"sites"or"species"or other ordination object recognized by scores.choices Selected three axes.col Colours of points.Can be a vector,and factors are interpreted as their internal numerical codes.ax.col Axis colour(concerns only the crossed axes through the origin).arr.len’Length’(width)of arrow head passed to arrows function.arr.col Colour of biplot arrows and centroids of environmental variables.envfit Fitted environmental variables from envfit displayed in the graph.xlab,ylab,zlabAxis labels passed to scatterplot3d.If missing,labels are taken from theordination result.Set to NA to suppress labels....Other parameters passed to graphical functions.DetailsFunction ordiplot3d plots static three-dimensional scatter diagrams using scatterplot3d.Func-tion uses most default settings of underlying graphical functions,and you must consult their help pages to change graphics to suit your taste(see scatterplot3d).Function returns invisibly an object of class ordiplot3d which inherits from ordiplot.The re-sult object contains the projected coordinates of plotted items and functions to convert3D data to 2D(see scatterplot3d).Function will display only one selected set of scores,typically either"sites"or"species".Examples show how to use the invisible return object to add another set of points to the projected plot.In constrained ordination(cca,rda,capscale),biplot arrows and centroids are always displayed similarly as in two-dimensional plotting function a.Alternatively,it is possible to display fitted environmental vectors or class centroids from envfit.These are displayed similarly as the results of constrained ordination,and they can be shown only for non-constrained ordination.The user must remember to specify at least three axes in envfit if the results are used with these functions.The function has a scores method to extract the projected coordinates from the invisible return object.Standard vegan functions can be used with the returned object.You can use any function from the ordihull and ordiarrows families(see Examples).ValueFunction ordiplot3d returns invisibly an object of class"ordiplot3d"inheriting from ordiplot.The return object will contain the coordinates projected onto two dimensions for points,and the projected coordinates of origin,and possibly the projected coordinates of the heads of arrows and centroids of environmental variables.The result will also contain the object returned by scatterplot3d,including function xyz.convert which projects three-dimensional coordinates onto the plane used in the current plot(see Examples).In addition,there is a function envfit.convert that projects a three-dimensional envfit object to the current plot.WarningPlease note that scatterplot3d sets internally some graphical parameters(such as mar for margins) and does not honour default settings.It is advisable to study carefully the documentation and examples of scatterplot3d.Author(s)Jari OksanenSee Alsoscatterplot3d,ordiplot,ordiarrows,ordihull.Examples###Default

Three-Dimensional Dynamic Ordination GraphicsDescriptionFunction ordirgl displays three-dimensional dynamic ordination graphs which can be rotated and zoomed.This function works with all ordination results from vegan and all ordination results known by the scores function.The orgl-prefixed functions add elements to the ordirgl graph similarly as ordi-prefixed functions in

ellipses,e.g.,0.95.If not given,sd or se ellipses are drawn.col Colour of items.This can be a vector and factors are interpreted as their internal numerical values.If the function has a groups argument,vector col is used foreach of these,and for other functions it is matched to points in ordirgl(seeDetails below).alpha Transparency of colour between0.0(fully transparent)and1.0(non-transparent).spantree A minimum spanning tree object from vegan spantree.cluster Result of hierarchic cluster analysis,such as hclust or agnes.prune Number of upper levels hierarchies removed from the tree.If prune>0,tree will be cut into prune+1disconnected trees....Other parameters passed to graphical functions.DetailsFunction ordirgl plots dynamic graphics using

scores function,or to any three column matrix.The orgl-prefixed functions add items to the opened rgl graphics device.Function ordirgl uses most default settings of underlying graphical functions in rgl.It plots only one set of points,but functions orglpoints and orgltext can add new items to an existing plot.The points are plotted using spheres3d and the text using texts3d which both have their own configuration switches and their general look and feel can be modified with material3d.The pointsize is directly defined by radius argument in the units of ordination scores in spheres3d,but ordirgl uses a default size of1%of the length of the longest axis,and this can be further modified by the cex multiplier.In constrained ordination(cca,rda,capscale),biplot arrows and centroids are always displayed similarly as in two-dimensional plotting function a.Alternatively,it is possible to display fitted environmental vectors or class centroids from envfit in both graphs.These are displayed similarly as the results of constrained ordination,and they can be shown only for non-constrained ordination.The user must remember to specify at least three axes in envfit if the results are used with these functions.Function orglsegments is similar to vegan ordisegments and connects points by line segments.This can be useful for regular transects.The colour of segments can be a vector which corresponds to the groups and will be recycled.Function orglspider is similar as vegan ordispider:it connects points to their weighted centroid within"groups",and in constrained ordination it can connect"wa"or weighted averages scores to corresponding"lc"or linear combination scores if"groups"is missing.Function orglellipse is similar as vegan ordiellipse and draws ellipsoids of standard deviance,standard error or con-fidence regions for groups.At least four points are needed to define an ellipsoid in3D,and even these will fail if all points are strictly on2D.The col argument for both of these functions can be a vector corresponding to the groups.Function orglspantree adds a minimum spanning tree from vegan spantree.This a3D equiv-alent of lines.spantree.Function orglcluster adds a hierarchic cluster tree from hclust or related functions.This is a3D equivalent of ordicluster.The col argument for both of these functions can be a vector corresponding to the

C E NTER NEWSuly 2008ContentsCoverArticlesOld Geezerby George King(No, this is not a portrait of a typical stereographer, even though we are gettingolder! See article page 3.)Center News is published quarterly as a benefi t forFriends of the Center :3D Center of Art & Photography1928 NW Lovejoy, Portland, OR 97209503-227-6667Copyright ©2008 3D Center of Art and Photography Vol. 5 No. 3 July 2008Editor: Diane Rulien Editor@The 3D Center is a 501(c)3 non-profi t corporation. Our vision is to provide a home for the past, present & future of three-dimensional imagery.2 Message from the Director by Paul Brenner3 “Window Shopping” by George King4 Friends Meeting Friendsby Mart McCann5 First Friends Appreciation Event by Diane Rulien6 New Selections from the Collections by Paul Brenner7 Helping Newbies Experience... by Diane Rulien8 Coming to the Center/Gift shop calendarpreparations for the NSA conference in Grand Rapids. I very much look forward to meeting many of you there. Several of the Center’s Board members (who I’m sure you have already met) will be there as well. We also look forward to the opening of the next exhibition, “Window Shopping” by George King. His striking anaglyphs, shot with a single digital camera slid along store windows in the U.S. and Europe, are as drolly humorous as they are technically masterful. I’m sure the cover image brought a smile to your face.This June the 3D Center hosted “3D Photo Booth.” A spin-off of “3D Photos with Santa” which takes place in December, the summer Photo Booth was so successful we plan to make it an annual event as well. Over 30 people and groups had their photos taken and some of the sample images are posted on the Friends Only section of the 3D Center website. Events like this help us to make 3D photography accessible and interesting for a general audience, which is, after all, why the 3D Center exists.It’s not all fun and games here all of the time (darn ;-!) as a subcommittee of the Board and I have been meeting recently to discuss long term planning and strategizing for the future of the 3D Center. I must admit, the plans are ambitious, but with a dedicated base of supporters like you, I know we can make large strides in the next few years. The resulting goals and timetables where submitted to the Board of Directors which provided unanimous approval.One of the Board members participating in these meetings was Ray Zone, a newly elected member of the Board. Ray (who telecommutes to meetings here in Portland from sunny L.A.), is full of new ideas for programs the Center can develop and ways to promote these activities. We welcome his energy and enthusiasm!The 3D Center has recently had some notable success in fundraising for public educational programs. Many thanks to the Portland-based J.W. & H.M. Goodman Family Charitable Foundation for a $5000 award to expand outreach to schoolgroups, offer scholarships to local students to take 3D Center classes, and offer additional educational opportunities during the 2008-2009 school year.We also recently received a $1000 award from the Multnomah County Cultural Coalition to repeat a successful program of free admission weekends that was fi rst organized in spring 2007. This MCCC Cultural Participation grantallows us to make 3D Center programs accessible to all residents of Multnomah County (the greater Portland area) regardless of their ability to pay the admission fee. This initiative is funded by the Oregon Cultural Trust, an innovative program that allows donors to qualifi ed non-profi ts in the state (the 3D Center is on this list) to make a matching contribution to the Trust and thereby earn a hefty credit on the amount of state income tax due. If you live in Oregon and want to learn more about this program, check out .Personal thanks must also be given here to the Regional Arts & Culture Council in Portland which has awarded me a Professional Development grant that will partially fund my trip to Grand Rapids for the NSA convention. It will be a great opportunity for a 3D neophyte like me to learn techniques, see tons of 3D imagery, and, of course, meet some of you.Thanks to all of you who have already responded to the membership renewal campaign mailed out several weeks ago. The number of responses has been terrifi c. If you haven’t yet made your renewal contribution, please do so. You don’t want this to be your last issue of Center News , do you?Hope you have a great summer.Paul BrennerDirectorHello Friends of the 3D Center:“Window Shopping”Just one of the things George likes to do...Autobiography by George KingI was raised in theSan Franciscoarea in the postWW2 era where I wasexposed to photographyby helping my parentsaround their professionalphoto studio. I rememberagitating chemical trayswhile being just tallenough to reach thetrays. They mostly shot weddings, school groups, andthe typical graduation mug shots. My father did enjoy artphotography, however, and attended workshops conductedby Ansel Adams. My father worshipped the man, and madesure I had the opportunity to meet him.I kept up my interest in photography during both myschool and early work years, but managed to develop anallergy reaction to the chemicals by my late twenties. Thatwas the end of any aspirations, but not my passion forphotography.I was an art major in college, and used that interest tomake a living for my entire working career. After movingto Portland in the early seventies I started a companydesigning and manufacturing jewelry for all the majordepartment stores, gift shops etc.I changed direction in the mid eighties, moving intolighting design, first designing for, and later managinga local company. In the early nineties I started my ownlighting design and manufacturing company, using theproceeds from a patent I held for the invention of anenergy efficient lighting concept. My company, which isstill located in Portland, specializes in period and antiquefixtures for public buildings and other restoration projects.At my leaving in 2007, I turned the company over to theperson that helped make the company a success.My interest in photography was rekindled by digitalphotography, first taking pictures during the many tripsarranged by my wife over the past decade. In the past fewyears I found that taking pictures became my reason fortravel. My time between the month long trips was absorbedby the required processing and printing, so I just didn’t haveany time left for my business. I now give my energies to anever widening interest in photography.I was introduced to 3D photography by the openingof the 3D Center in what was my neighborhood. I took allthe classes provided by Shab Levy, and with his guidance,built a digital 3D camera. I discovered, however, thatI preferred the challenges and spontaneity of shootingwith a conventional digital camera, rather than dependingon specialized 3D equipment, so that I can mix up myphoto shooting sessions with both 3D and conventionalphotography.The mannequin photographs which are the focus of“Window Shopping,” on exhibition at the 3D Center fromJuly 3 through September 6, came from my fascination witha number of films that have as a theme either a mannequincoming to life, or some lonely guy living a fantasy peopledby mannequins. Mannequins are the “beautiful people” inour urban environment; they are the best dressed, alwaysat play, while we rush through our day. It’s not difficult toimagine these silent onlookers comparing comments afterhours. However, these happy folk are quickly disappearingfrom our stores and window displays, replaced by headlessdress forms and photo back-drops. I understand they havebecome too expensive to purchase, and require too muchtime and expertise to maintain.My current project is very different; macrophotographs of objects which in two dimension are nonobjective abstractions. These same photos, when viewedwith anaglyphic glasses, become understandable as a formor object.Friends Meeting Friends by Mart McCannAs a regular feature, we hope to acquaint you with other Friends of the Center in the community of stereo photographers and collectors. This is the third in a series.Portrait Mart McCann (right) by Larry Fergusion“One’s smart, the other’s funny.” That’s inscribed on a stone marker outside the house Bob Venezia shares with his wife, Mandy, one of the country’s best criminal defense attorneys. His admiration for her is almost palpable as he describes herselection for the ACLU’s John Adams Project. As a long-time, card-carrying member of the ACLU myself, it was hard not to go off on a tangent. But we’ll stick to the funny one, as he’s the stereographer.My editor, bless her heart, asked me to write a profile that shared more than how someone got started in stereophotography and why they think the 3D Center is so important, so I looked around for a truly unique personality. I knew Bob Venezia was funny. We are both members of the Puget Sound Stereo Camera Club, and Bob gets a laugh at every meeting, but I had no idea he was that funny. In 1979, Bob came to San Francisco for a social services job that never materialized and found himself “…with no money and no prospects, but I knew a few magic tricks.” So he began performing at the corner of Beach and Larkin, outside Ghirardelli Square. Within a short time, he was performinginsideTheCannery a fewblocks away.Bob’s earliest character was Polaris the Venezia’s Mesa Arch at Sunrise has won awards in several stereo exhibitions.Bob Venezia as “El Profundo.”Dodecahedron by Bob Venezia. Tom Noddy, The Bubble Guy and subject of this portrait, helped Bob connect with the west coast Vaudeville community.Wizard. Subsequent years brought on a menagerie of magical characters, including Alfredo Fettuccinni, a boy-man with an overabundance of enthusiasm, and ElProfundo, whom Bob describes as being “powerful and angry,” but apparently funny, too.Around 1982, Tom Noddy, “The Bubble Guy” came through town and told Bob about the west coast new Vaudeville community, which gravitated toward the Oregon Country Fair, an arts and crafts festival with a large entertainment element. The OCF is a juried festival, and once accepted, artists frequently hold onto their spots for years. Well guess who’s going back to the Oregon Country Fair for the first time in 15 years? Yes! El Profundo! I was ready to start looking for a hotel room in Eugeneuntil Bobtold methat he’ll beperformingat the same time the NSAconvention will be held in GrandRapids.Sometime in the early 80s, Bob started performing withBliss Kolb, a skilled craftsman,award winning designer, and “my best friend.” The two were known as Laughing Moon Theatre, and theirletterhead proclaimed, “In a city full of crazy people, we’re professionals.” Their show, which Bob says worked best in small theatres of about 100 seats, was called “Sleep Tight – an evening of magic, video and deranged comedy.” It opened with a scene out of Kafka’sMetamorphosis, in which a man wakes up in his own bed to find himself transformed into a giant insect. In “The Production of Any MealCalled From a Gentleman’s Top Hat,” Bob played a current-day “wrangler”of a turn-of-the-last-century magician.Bliss, as the magician, was wheeled onstage in an exquisitely-crafted box of his own construction, an old theatre trunk covered with travel stickers. An audience member was called upon to choose the meal from a menu (#3 wasthe only item on the menu), which was then produced from the contents of the top hat. Sure-fire, bullet proof comedy.So how does a performance artist in San Francisco wind upas a Seattle-based graphics designer? “Sleep Tight” was brought to Seattle by The Flying Karamazov Brothers, and Bob met Mandy (the smart one) at one of the first shows. As one of Microsoft’s former “perma-temps,” Bob now works for a year and then takes 100 days off.Those of us who are lucky enough to see Bob’s stereo images on a regular basis are all familiar with his spectacular night photography,particularly of carnival rides at the Puyallup Fair. “Carnival rides are the perfect subject, they fire on all the cylinders for me as they’re somewhat surreal. 3D makes me feel like a kid again, and so do carnival rides.” Most of his exposures are 4 seconds on ISO 100 film at F16. “I like how much happens in four seconds, although eight at F22 works well, too.”Seattle Center, where the ’62Worlds Fair was held, is another favorite subject. “I keep finding more and more great shots down there.” The monorail gliding past the Experience Music Project building, designed by Frank Gehry, is just one example.“I was out just last night. I got a view of Seattle from the 12th Avenue Bridge. The bridge is painted industrial green, but in the long exposure, it looks like solid gold.”When our conversation ended,Bob promised to send me an image of El Profundo. Accompanying the file was the following note: “Utah Phillips, an old friend of mine, once said it’s important to keep track of who youowe, and there are a couple of people that should be mentioned in any profile of me as a 3d photographer. One is Susan Pinsky, who harassed me into finding my local 3d club. And the other is Don Lopp,without whose amazing generosity and friendship, I would be nowhere near the photographer I am today.”No, I never asked Bob how he got started in stereophotography. I never even mentioned the 3D Center, but Bob is a Charter Member of Friends of the Center. Enough said.El Profundo will beperforming at the Oregon Country Fair () which runs from July 11-13 just west of Eugene, OR. The Flying Karamazov Brothers are performing in Washington state throughout July and early August (). If you go to and click on Theatrical State Sets, you can see the Kafka scene. And to learn more about the ACLU’s John Adams project, see /johnadams.First Friends Appreciation Event Scheduled at the close of the PSA Convention in Portland, ORIt is long overdue, but as you can well imagine we have been pretty busy the past 4 years! On Sunday after-noon, September 7, a Friends appreciation event will be held at Rich and Susan Dubnow’s home in Beavercreek outside of Portlad. The event will be a time to celebrate what has been accomplished, talk about what is going on in the stereo community and look ahead. Of coursethere will be food and drink - a barbeque, salads, desert and some beer and wine. The entertainment is still in the planning stages, but Rich has offered to fire off his cannon (after giving notice to his neighbors!) Rich’s business, Im-age 3D is located within walking distance of his home so by Diane RulienThe Center will be helping with programming for the stereo theatre at the PSA Convention in Portland. Several shows from the Center’s collection will beprojected. While the convention is in town, visitors to the Center will see JohnHart’s Liquid Magic in the Center’s stereo theatre. Hart’s show was a great success when first presented at the Center in 2006. George King’s Window Shopping will be showing in the Center’s gallery (see article page 3.)there will be an opportunity to see his operation and ask questions.The PSA Convention runs from August 31 through September 6 in Portland so it is hoped that those from out of town will stay an extra day to enjoy this festivity. Not only are many Friends of the Center PSA members, but the PSA Stereo Division is a Club member of Friends of the Center . The event is open to all Friends of the Center and their guests. If we have your current email address, you will be getting an emailed invitation. Information will also be available on the Friends Only page of our website. If we don’t have your current email address, go to and click on the link at the top of the page, “Contact,” and email Paul with your up to date contact info. Plan to join the fun!New Selections from the Collections by Paul BrennerThe 3D Center is now nationally recognized as one of the premier repositories for historical information, images, and equipment related to stereoscopy. We are therefore frequently contacted by people hoping to find a permanent home for 3D items for which they no longer have space or that they have recently acquired from an estate. We encourage these types of donations to the 3D Center and work continues here to catalog the collection and display select items in the museum when possible.We have recently been given two exceptional items, one of which is now on display at the 3D Center; a well-known collection of stereoviews by the Keystone View Company: “World War through the Stereoscope.” Keystone began publishing this series of stereoviews in 1923 in four collections of various sizes (75, 100, 200 and 300 cards). The one now owned by the Center is the 100 card set, in a box crafted to appear as a stack of 2 black books, the most popular design forholding these boxed sets.The images in this series werephotographed for Keystone byAndrew S. Iddings and the text waswritten by Joseph Mills Hanson.Each card has detaileddescriptive information on the reverseof views from various battles, militaryformations and operations, medicalfacilities, scenes of destruction andeven some gruesome images ofcorpses. The descriptive informationthus provides an extensive historyof World War I, while also offeringan interesting, early 20th centuryperspective on the march of time.For example, text on the reverse of“French Troops Inspecting a WreckedZeppelin” #18632 includes this bit offoresight regarding the zeppelin, “Itsgreatest service will be performedin time of peace. Before many yearsKipling’s ‘Night Mail’ will become areality. The air will be marked out inlines of travel as the ocean is today.From New York, London, Paris andother metropolises huge liners of theair will fly to all points of the compass,ships 200 yards long, traveling 100miles an hour and carrying tons ofmail and scores of passengers.”In conjunction with thestereoview sets, Keystone published a500 page book in 1927 which includesthe images, descriptive information,maps, and a guide to studying the warthrough stereo imagery (this book iscurrently available on CD). Manyimages from the series can also beseen at /~j.p1/ww1/worldwar.html.“World War Through theStereoscope” was donated to the 3DCenter by Ron Palmer of CottageGrove, OR. Though not a collector ofstereoscopy, Ron acquired the set afterhis mother passed away last year. Ronremembers viewing them as a child inthe Portland home of his grandfather,who originally purchased them in themid-1920s after his son (Ron’s uncle)Learning to Use Gas Masks: The officer before us is instructing his squad in the use of gas masks. Thorough drill in this is of the utmost importance, for a few seconds delay in adjusting his mask in a gas attack ay incapacitate a soldier for service and subject him to weeks of agony, if not death.The Germans were the first to use poison gas in the war, expelling it from metal tubes and trusting to the wind to carry it down upon our allies. This method was soon discarded in favor of gas shells, which they used extensively, sometimes one shell in every three being filled with gas. It became necessary to equip every man in our army with a mask and drill him in the use of it. These masks fit so closely that air cannot enter the nostrils except through the breathing tube. The general principle on which they are constructed is this – that the inhaled air is drawn through certain substances which absorb the gas before it can get into the mask, while the breath which a soldier exhales escapes from the mask through a rubber valve opening only on pressure from the inside. The mask is carried in a canvas case, ready for instant use. A soldier, expert in the use of his mask, can put it on in about ten seconds.Soldiers do not like to wear the mask and will often take great risks rather than be annoyed with them, for even the best of them add somewhat to the difficulty of breathing. Then too, moisture which accumulates inside the mask dims the eye glasses and it becomes difficult to see. Throughout the war there was constant effort to produce a gas against which no mask would be effective. The Germans used phosgene, mustard gas, lachrymal gas and others, but our chemists devised masks effective against each.(information from the back of this stereocard)had served in the Great War. Thank you Ron for this fascinating piece of 3D history!Another notable addition to the collection at the 3D Center came from Raymond Welcox of Portland who happened upon the Center earlier this year and returned several weeks later with the donationof one volume (10 reels) of the“Stereoscopic Atlas of HumanAnatomy” published by theSawyer’s Company (View-Master)in Portland in 1954.This ground-breaking seriesof reels and descriptive books withdetailed diagrammatic drawingswas the brain-child of View-Master inventor William Gruber in partnership with David L. Bassett of the Stanford School of Medicine. Begun in 1948 and not completed until 1962, the entire series consistsof 221 View-Master reels with 1554color stereoviews of dissections of every body region. The images werepainstakingly created by Gruber andBassett with high-resolution Kodak film that provides remarkable clarity even 50 years later. These stereoscopic images are still consideredthe definitive dissection collection available to medical students and instructors. Bassett images can be found in most anatomy textbooks and as the trend towards using fewer cadavers in medical schools continues, the use of these images is growing.The original collection of images now belongs to Stanford University (donated by Bassett’s children upon his death in 1966) and is under the care of Robert Chase, curator of the Bassett collection and also a Friend of the Center . We are currently exploring the possibility of exhibiting part of the collection at the 3D Center in 2009. You can preview some of the images (alas, in 2D only for now) at the following site: /photos/stanfordmedicine/setsSources used for this article:Hickman, Sandy,“World War IKeystone View Stereocard,” Faded Rose Antiques website, 20 June 2008.Leonard, Robert James, “Verdun:Then & Now,” Stereo World , V ol. 24, # 3. White, Tracie, “Dazzling dissection images from famed Bassett collection now online,” Stanford School of Medicine website, 20 February 2008.Helping Newbies experience the Fun of 3DAn enlarged stereo pair from one of the reels included in with the book.The Center’s Board and staff search constantly for new ways to bring the uninitiated to the world of 3D. Classes in various aspects of stereoscopy, public events including 3D pic-tures with Santa in December and most recently the 3D Photo Booth weekend allow visitors to experience the fun of 3D and take home a souvenir of the experience. The Center’s most re-cent grant will allow us money to publicize 3 weekends of free activities to the public. V olunteers will make it happen. Each time the Center schedules and promotes such events, the world of 3D gains new enthusiasts.Purists will point out that the images are not perfect. They were taken with a Pentax digital camera using a lens in a cap. This system does allow the images to be taken and a stereo pair printed out while the visitors wait. However, the black line between the images and no time for making pho-toshop corrections, means that the novice may be delighted with the result, but an experienced stereographer wouldbe discontent.
