I want to visualize an unstructured grid made of tetrahedra. I would like to use some kind of plane and see all the tetrahedra that are at the right (or left) of the plane. To check is the tetrahedron is right or left of the plane, I will use its circumcenter or other kind of metric, doesnt matter. The idea is to see something like this:
It looks like an easy task, but I havent been able to do it and haven’t found any solution searching. Any support would be much appreciated.
