volume or point detection in a non-convex polyhedron

Hello,

We have a polyhedron obtained with the isosurface function. That is why we have a list of vertices and faces. We would like to either calculate the volume of the polyhedron defined by faces and vertices or detect which points are inside the polyhedron.

Unfortunately, the polyhedron is not necessarily convex.

Thanks

What about for volume?
