out how. Is there a way to remove chunks out of a volume? Not by scalar
though. I could use a sphere or other builtin implicit function if
necessary, but it seems that the other methods of doing stuff like this
are not set up to work with vtkVolume's (as they are derived from
vtkProp).<br>

Can you explain what you mean by "not set up to work with
vtkVolume"? <br><br>
You should be able to use either cropping (axis aligned planes - this is
specific to volume mappers) or clipping (arbitrary planes - limited to 6
by OpenGL - this is supported at the superclass level for all 3D mappers)
However, I suspect it will be hard to set up clipping planes to do what
you want and most likely you will need to apply a sequence of imaging
filters to your vtkImageData in order to isolate the structured you are
interested it. You may want to also look into ITK for this
(<a href="http://www.itk.org/" eudora="autourl">www.itk.org</a>).<br><br>
