These clip filters depend on the resolution size, I modified your
example to use a higher resolution image. I'd like to add this to the
VTKExaamples repo if is OK with you. I will acknowledge your

I've attached a simple program that demonstrates the problem and a screenshot of the output. The program generates a vtkRectilinearGrid and pipes it through vtkTableBasedClipDataSet with its clip function set to two perpendicular planes. The result should have a concave right angle, but diagonal facets appear instead.
