Oh, sorry for this. I'll post VTK related questions to that mailing list from now.

This is a severe limitation, because if you want to render 2 (or more) views of the volumetric data, you need to allocate it two (or more) times and this is quite prohibitive in most scenario.

Anyway, thanks for the reply,

You are posting to the wrong mailing list. VTKEdge has its own one:

I think if it worked with vtkOpenGLVolumeTextureMapper3D it was by
chance. You cannot reuse the same mapper in two different render
window. At the OpenGL level a
render window is attached to one OpenGL context and each mapper caches
some OpenGL resources specific to this OpenGL context.
