sorry if the question is duplicated, I don't even know what to search for solve this problem.
I have for example 10 planes with their equation: Ax + By + Cz = D and a list of 3D points. Those plane can make regions, some of them closed, and others not, the task is to count the number of points in each region.
I just need some ideas about how to solve, or if there is an algorithm for that.
