[vtkusers] vtkClipDataSet quality

[Maple Raymond C LtCol AFIT/ENY]

Hello,

   I have a question about the proper use of vtkClipDataSet.  I am using
this function to clip an unstructured tet grid against multiple planes.
I have found that if I clip against multiple planesat one time, either
through a vtkPlanes object or a vtkBoolean union of planes, the
resulting clip is not "clean."  Cells that get clipped by two or more
planes are not reduced properly.  However, if I construct multiple clip
objects and clip one plane at a time, everything turns out as expected.
Is this behavior by design, or is it a problem with the clipping
algorithm?  What is the recommended way to clip to a collection of
planes, either in the form of an axis aligned bounding box or
arbitrarily aligned planes?

 

Thank you.
