[vtkusers] Clipping of a volume

[Rhys Thomas]

Hello all,

    I was wondering if anyone could provide some hints on the following 
problem: I wish to clip an instance of/ vtkStructuredPoints/ using a 
/vtkPlane/. I want the output to be an instance of /vtkStructuredPoints/ 
so that I can insert it into my graphics pipeline in place of another 
instance of /vtkStructuredPoints/ because I am performing other 
operations on the data (changing opacity of certain voxels, contrast 
stretching). I am currently using /vtkRenderer::AddVolume /to add a 
/vtkVolume/ to the pipeline. I have tried variations of /vtkCutter, 
vtkClipVolume /and/ vtkProbeFilter, /but with disappointing results. 
Does anyone have  any suggestions as to the quickest (i.e. least 
processor intensive) solution to this problem?

Thanks

Rhys
