For 2D geometries it is possible to use ''inpolygon'' function to
determine regions contained in another region. Is there such a
function in 3D geometries?

If the domain is convex, then inhull
will do it.

If you do not have a convex domain,
then it becomes harder to define the
region. There are ways to do so, but
it is harder.
