[Paraview] vtkCutter

[Heiland, Randy]

Silly me. I see now that it’s just a matter of using multiple Clip filters, using planes with orthogonal normals, resulting in the desired boolean set of points. Still need to figure out how to cap the clipped glyphs though…

More specifically, my current use case is a bunch of spheres (representing biological cells) inside a spheroidal tumor. I’d like to cut out an octant, for example, from that spheroid to be able to peer inside better.

I just used the Box option of the Clip filter, because the Plane option seems to define an infinite plane (via Point and Normal). But the Box params (Position, Rotate, Scale) is not intuitive for my use case. Ideally I’d like to be able to specify a Corner and 3 Vectors. And, eventually, I’d like “cutter” results, where the spheres/cells are actually cut and capped.
