[vtkusers] limiting the volume of vtkContourFilter and Volume Rendering

[Moritz Bernard Fricke]

Hello users,

i have a problem concerning vtkContourfilter and volume rendering. I want to crop the volume that is rendered, but i don't have parallel planes to crop. i have to visualize a complex room. The walls of the room are polygons. How can i use the those polygon as cropping planes?

Thanks in advance,

Moritz
