Volumetric datasets are converted to surfaces using vtkDataSetSurfaceFilter.

If the STEREO_TYPE environment variable is set to "CRYSTAL_EYES", "RED_BLUE", "INTERLACED", "LEFT", "RIGHT", "DRESDEN", "ANAGLYPH", "CHECKERBOARD", or "SPLITVIEWPORT_HORIZONTAL", the corresponding VTK stereo type is set via vtkRenderWindow::SetStereoType().

If there is a scalar data array defined for the dataset, it is displayed on the resulting surface with a white-to-red colormap.

If the surface lacks normals, they are added with the vtkPolyDataNormals filter.
