Hi vtkusers~

Have a question.
I put to use clipping planes in vtkVolumeRaycastMapper class.
How can be clipping except planes overlapping?

An example..
first plane => | (middle height form) , second plane => -- (middle width
form)
the sum => -|-   (cross form)
overlapping part => the right from a lower part

pipeline =>
vtkVolume16Reader->vtkPiecewiseFunction->vtkColorTransferFunction->vtkVolume
RaycastCompositeFuntion->vtkVolumeRaycastMapper->vtkVolume

clipping planes pipeline => vtkPlanes, vtkPoints, vtkFloatArray
