volume render with 3D texture mapping
vtkVolumeTextureMapper3D renders a volume using 3D texture mapping. This class is actually an abstract superclass - with all the actual work done by vtkOpenGLVolumeTextureMapper3D.
This mappers currently supports:
- any data type as input
- one component, or two or four non-independent components
- composite blending
- intermixed opaque geometry
- multiple volumes can be rendered if they can be sorted into back-to-front order (use the vtkFrustumCoverageCuller)
This mapper does not support:
- more than one independent component
- maximum intensity projection
Internally, this mapper will potentially change the resolution of the input data. The data will be resampled to be a power of two in each direction, and also no greater than 128*256*256 voxels (any aspect) for one or two component data, or 128*128*256 voxels (any aspect) for four component data. The limits are currently hardcoded after a check using the GL_PROXY_TEXTURE3D because some graphics drivers were always responding "yes" to the proxy call despite not being able to allocate that much texture memory.
Currently, calculations are computed using 8 bits per RGBA channel. In the future this should be expanded to handle newer boards that can support 15 bit float compositing.
This mapper supports two main families of graphics hardware: nvidia and ATI. There are two different implementations of 3D texture mapping used - one based on nvidia's GL_NV_texture_shader2 and GL_NV_register_combiners2 extension, and one based on ATI's GL_ATI_fragment_shader (supported also by some nvidia boards) To use this class in an application that will run on various hardware configurations, you should have a back-up volume rendering method. You should create a vtkVolumeTextureMapper3D, assign its input, make sure you have a current OpenGL context (you've rendered at least once), then call IsRenderSupported with a vtkVolumeProperty as an argument. This method will return 0 if the input has more than one independent component, or if the graphics hardware does not support the set of required extensions for using at least one of the two implemented methods (nvidia or ati)
