Re: Get Interior Points

Given a set of points in 3D (which resembles a flat surface
in 3D), how do I find the set of interior points contained
in this surface?

I've tried convhulln to no avail (some surfaces are defined
by only 3 vertices, which convhulln does not permit).




Use a change of coordinates to transform it to a plane in
R^2 and then use inpolygon.
