[vtkusers] vtkVolumeRaycastMapper : How I can divide the screen in two parts ?

[Francesco Piccolo]

Hi,

I need to divide the screen in two parts, in order to elaborate the left
part with a CUDA raycast algorithm and a the left part with the
VtkVolumeRayCast algorithm.

How I can change the mapper in order to obtain the visualization and
elaboration only of an half part of the renderWindow  ?

I have tryed to change the pointer ImagePtr in VtkVolumeRayCastMapper.cxx,
but I haven't obteined a good result.

I attach in the link a screen about what I want to do. ----->
