[vtkusers] VTKEdge volume mapper cannot work with multiple render window?

[Francois Bertel]

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.
