"WebMay 23, 2024 · If you polytope is convex, this answer should work. Otherwise you can always do rejection sampling: Sample a point from the bounding box, check whether it's inside the polygon. That gets really slow for high dimensions and "unboxy" polytopes though, because the bounding box potentially has a huge volume compared to the region you're interested in.
