Note: The current algorithm does not support coincident volumes or volumes in perspective. (See #!Ldisplay,dxall807 h Display #!EL for a discussion of Data Explorer rendering capabilities.) #!N #!N The specified object must contain a "colors," "front colors," or "back colors" component. Many modules add a default color. In addition, volume rendering (i.e., of cubes or tetrahedra) requires an "opacities" component. For surfaces, the lack of an "opacities" component implies an opaque surface. #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* camera #!EF #!EF #!I50 #!N is the camera used to create the image. Note: A transformed camera cannot be used for this parameter. #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* format #!EF #!EF #!I50 #!N is reserved for future use. #!I0 #!N #!N #!N #!N #!I0 #!N Notes: #!N #!I30 #!N 1. The rendering properties of an object (e.g., shading) can be changed with the Options or Shade module (see #!Ldisplay,dxall807 h Display #!EL ). Render always invokes the software renderer and so ignores the "render mode" attribute. #!N #!I30 #!N 2. Render creates 24-bit images if the DXPIXELTYPE environment variable is set to DXByte (the default is 96-bit images). #!N #!I30 #!N 3. If you use the Display or Image tool rather than the Render module, Data Explorer will automatically choose a hardware-appropriate format for you. It is generally preferable to use one of these tools unless you want to operate on the image itself. For example, filtering the image or arranging several images together requires the Render module. #!N #!I30 #!N 4. The interactive image-manipulation options provided by Data Explorer in the user interface require the Image tool.
