Key words: computer virtual reality technology building design
Lead it
In modern architecture design, application of computer technology to the architectural design process has been more mature, to use a computer aided architecture design, the designer can put main energy to the creation and design of buildings, avoid in dealing with the architectural design of the tedious work of calculation, drawing, data storage, which can effectively improve the design efficiency of architects and design quality. Design of computer design, can use electronic display, or other graphics device full display design, and designers can to reasonable plan for review and modification. So using virtual reality technology in architecture design can make the architecd has a feeling of intimacy.
1、The introduction of virtual reality technology
The so-called virtual reality technology is the real environment virtualization, in the modern information technology, virtual reality technology has been well used. The use of virtual reality technology can be objects or ideas through the visual, auditory, and other aspects for rendering can let a person very intuitive understanding of object features and functions. The emergence of virtual reality technology, essentially changed the traditional way to pass information to the omputer. In interactive virtual realitylogy in computer application, imaginative immersion.Along
with societys continuous development, also began in the architectural design applied to the virtual reality technology, virtual reality technology in the architectural design of onstruction projects can be the shape of the structure, construction process and so on presented in a more intuitive way. Must carry on the nage thinking in architectural design, and considering the users experience as the core, is a series of innovation process, including planning, design, construction, maintenance, etc. Huge cost and irreversible executable program, can 't appear too many errors, virtual reality can create and reflect the virtual world of the computer system, the virtual world as a whole virtual environment or all objects of a given simulation, make full use of computer aided design and virtual reality, can reduce the labor intensity of designer, shorten the design cycle, improve the design quality and save investment. Virtual reality chnology has been widely applied in architecture design.
2, display the structure of the whole information
At this stage of two-dirnal, three-dimensional form of expression, can only transfer building part attribute information, and can only provide a single scale building information, using virtual reality technology can show a living virtual building, make the person produces the feeling of immersive, design is not just a matter of designers, households, management department can have the effect of aid decision making.
3, browsing over a long dista
Designer to design the building and project units can communicate with each other, achieve remote browsing through the world wide web, also can develop in computer language and virtual ality modelling language integration, virtual reality used in Internet network to improve the universality and practicability
4、 real-time scheme comparison
In the engineering construction design, design usually draw up the several design meet the designrequirements are different to the use of virtual reality technology, these solutions can be switchable and corresponding comparison, thus can choose according to qualification. In compare he construction scheme, construction of virtual reality technology is a distinct feature and shortage of present construction plan can be a sketch, allowing designers to make further
decisions.In the practical application of virtual reality technology in architecture design, not only can carry on the detailed comparison to the design, can also according to the requirement of the designer on the appropriate modification.
5, and special man-machine interface interaction
The bridge of the man-machine interface is the user and the computer, it is on behalf of the userintent conversion and the execution of a computer program, a good man-machine interfacereduces the time to users on the system of learning and enhance the system efficiency. In virtual reality technology in architectural design, must have user mode. Users direct access to virtual reality, carries on the observation and interactive operation, in the first person way of observation, and immersion of virtual reality observation hidden interface, only when in use;
(2)an agent model. In the virtual reality, often because of immersion and reality environment perception gap, and space lost pheon. so that the user is unable to grasp the status of virtual reality, virtual environment information agents to provide space for, in the first and second person way of observation, carries on the observation in the virtual environment; (3)the monitoring mode. Users in the form of the third person, monitor all real state in the virtual reality, and virtual content monitoring and control, and the generation of interface and types of virtual reality, there is no absolute relationship (4)in operation mode. Puts control interface of virtual reality, virtual reality, for the simulation of operation simulation, users in the first person operating mode, to control the virtual objects Virtual reality system basically has two kinds: model type and image type. Model type virtual reality, virtual reality modeling language (VRML) as the main description language, and makes the architectural design of available computer 3 d modeling, rendering and 3 d construction drawing and database, and using virtual reality technology to link to the database as a real-time definition that is associated with more information in the layout and contents of the three-mensional world, make it in an interactive,the virtual reality modelling language browser starts, it will be the information in the virtual reality modelling language interpretation into virtual reality modelling language of space geometric description of buildings, once the VRML spacplained by the users browser, it will provide a real-time display a second can show many times. so, there will be an activity of the user' machine
6, application instanc
Virtual reality technology to start faster, Dutch Eindoven Calibre research institute at theuniversity of using virtual reality technology in design and consulting, they developed software package consists of a set of classes CAD functions, called CAAD software, for the structure of the creation, modification and visualization toolkit, it supports Auto CADDXF file input and output, object. Have used the system modeling is a small city, specific target is in a river onsmall and medium-sized design museum. The city is composed of hundreds of building, located near the river on a slope, overlooking the island. First of all, digital maps of the city, create a basic Auto CAD model; Secondly, according to the real 3 d position arrangement of each building well as consideration of the slope contour; Again, plus the construction details, such as the door frame and window frame design, so that the standards to the aesthetic characteristics of the city. The application example for people to appreciate the achievements of the field and their rocess of the production of modern society, virtual reality technology has been applied to all walks of life, there is great potential because of the virtual technology, and engineering application in building with higher development prospects. But when using virtual reality technology, need hardware and software investment is large, and the repeatability is not higl. 7. the conclusion
With the development of the society, virtual reality technology application is more and more widely in various fields. Changing at present because of the computer information technology and Virtual reality technology can be used to computer the processing object and fast processing. In the field of modern architecture, architectural design is a complex process, but with the application of virtual reality technology matures, the designers in architecture can be drawing, data storage, such as work to a computer, thus effectively improve the efficiency of the designers work. To sum up Ith the development of science and technology, in the design of construction engineering when the use of virtual reality technology will only become more frequent, and the technology will also be increased gradually.。
