Mimics+3D+tools

General information on the operation of 3D ToolbarThe 3D toolbar is displayed at the right side of the 3D view.Toggle transparencyYou can show the 3D object opaque or transparent. Click on the button in the 3D toolbar to toggle between opaque and transparent view.You can change the transparency of the 3D object and make objects transparent. Drag the Transparency slider at the bottom of the 3D properties dialog. If the slider is all the way to the right, the 3D surface is opaque and nothing below the surface can be visualized. If the slider is all the way to the left, the 3D surface is completely transparent.ClippingClipping allows you to visualize the section in which you are interested. It can be used, to evaluate the gray values on the section boundaries or to look inside the model to get a better comprehension of the geometry. The section can be made along the different planes, axial, coronal and sagittal. Several clipping planes can be activated at the same enabling you to isolate thepart of interest.To enable clipping click on the Enable/Disable clipping button . The settings of the clipping can be changed in the clipping tab:ActiveBy default one axial clipping plane is active. To make more planes active, make sure to check the active iconThe position of the clipped plane in the 3D view corresponds with the position of the active axial, sagittal or coronal image. Scrolling through the 2D images updates the clipped plane in 3D. Alsonavigation on the clipped 3D is possible by clicking on visible parts on the 3D. When you rotate the 3D along the clipped plane, the visibility automatically reverses.TypeAs stated above you can select multiple clipping planes. For each view you can define two clipping planes. For each of the clipping planes, you can choose which objects need to be clipped. You can choose this by selecting the clipping plane in the list and changing the selections in the dropdown menu . All objects are selected by default.ClipBy default the direction of the clipping plane is defined by the viewing angle. The direction of the clipping plane can be locked by selecting a clip direction. Click on the clip icon to lock to a clipping direction or to unlock.LockThe location of the clipping plane is locked to the slice position. To unlock the clipping plane from the slice position, disable the lock icon . When the lock icon is disabled, you can determine the location of the clipping plane with the slider at the bottom of the clipping tab.TexturingYou can also choose between three texturing methods:When choosing No texturing, only the 3D Object is clipped and you can see inside the 3D Object. When choosing Object Texturing, a texture corresponding with the 2D slice is placed in the contours of the 3D Objects. When choosing Full slice texturing, the 3D Object is not clipped, but the whole 2D slice is visible in the 3D window.Note: This technique is only available in OpenGL and direct3D rendering (not in software). To check your rendering option, go to Option | Preferences and select the OpenGL or Direct3D rendering option in the 3D settings. To accelerate the performance of clipping, activate the hardware acceleration in the same dialog.Volume renderingVolume rendering allows you to quickly visualise your 2D image data as a 3D object without any segmentation. The 3D object is build up out of the voxels representing the dataset. The transparency of the voxels is determined based on their grey value.Volume rendering is a pure visualisation tool and cannot be used for anything else (e.g. exporting). You can find the interface for the volume rendering in the volume rendering project management tab:Defining the opacityThis interface shows a histogram which represents the gray values or Hounsfield units of the dataset. The transparency of the gray values is set by the opacity lines on the histogram. The higher a line is positioned the more opaque the voxels within that range will be visualised. In the first column the line representing the low Hounsfield values is positioned to the bottom. Subsequently the voxels are represented transparent. In the second column the line is positioned higher which makes the voxels opaque.Move a point Position a point click left and drag the point to its new positionAdd a point Click left on a line to add an extra pointDelete a point Right click on a point and select delete to delete a point Defining the colorThe graph below the histogram defines the color of the rendered voxels. You can choose a color for each point in the graph by right-clicking on the points and choosing Change Color. Mimics will then create an interpolated shading between the different control points. The same system for adding, moving and deleting bullets is available as for the opacity line.Predefined settingsOn the bottom of the volume rendering interface you find a dropdown list with predefined settings. The predefined settings are optimized for CT image and allow you to quickly select bone,soft-tissue or both.You can save your current setting as a predefined setting by clicking on the save button. To delete your predefined setting, select it from the dropdown box and click on the delete button.Show reference planesIt is possible to show in the 3D view the reference planes of the current position by clicking on the Show Reference Plane button . The reference planes take over the colors that belong to the different views:Axial RedCoronal OrangeSagittal GreenCross Sectional BlueParallel YellowThe reference planes that have to be shown can be selected in the 3D tab of the Preference settings. Only the reference planes of the views that are displayed can be shown in the 3D view.Select 3D viewWhen you click on Select 3D View button , a list with all possible default views is displayed. Selecting an item from this list will position the 3D object according to the selected position.Rotate viewThe rotate function is only available on a 3D object. There are different ways to select the rotate function:•right-drag with your mouse button•use the arrows-keys for precise rotation•use Home / End to rotate 10 degrees Left / Right•use Page Up / Page Down to rotate 10 degrees Up / Down•right-click in the 3D view and select Rotate View from the context menu•click on the Rotate View button in the toolbar•select View > Rotate View from the menu barToggle visibilityBy toggling the colored cubes in the 3D toolbar, you can make the 3D objects, with the corresponding color, visible or invisible. For every 3D object in the project there is a corresponding cube.。
