A system, method, and computer program product for determining a radial function and distribution of a three-dimensional object model. One method includes retrieving a three-dimensional object model in a CAD system and sampling random points on the surface of the object model. The method also includes determining a normal vector corresponding to each of the random points and determining a radial function corresponding to each normal vector and respective random point. The method also includes determining, by the CAD system, a radial distribution corresponding to at least two of the radial functions and storing the radial distribution and average values of the radial functions in the CAD system.
