[Paraview] vtkCutter

[Heiland, Randy]

Thanks. Actually, I did a poor job explaining what I want to do. I’d like to have *partial* clip planes (as opposed to “infinite" planes over the entire domain). 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’ve mocked up an example, using random points, and put the PV state file at https://github.com/rheiland/paraview_play <https://github.com/rheiland/paraview_play>  (along with some sample /images). 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.

So perhaps, I need an alternative pipeline for my use case. Suggestions welcome. For that matter, am I mistaken in thinking I can do what I want using OSPRay spheres?

thanks! -Randy
