I guess you could use the AABB-tree to extract all the faces intersected

by your small poly and create a smaller mesh out of those faces (+ some

extra faces to make it a topological disk). Then you can use the

coref+intersection to get a close mesh for which you can compute the

volume.

However, I'm afraid you won't have the runtime you expect.
