Detailed Description

API algorithm for intersection of two surfaces by intersection of their triangulations.

Algorithm provides possibility to intersect surfaces as without the precomputed sampling as with it.

If the numbers of sampling points are not given, it will build the net of 10x10 sampling points for each surface.

The intersection is done inside constructors. Before obtaining the results of intersection it is necessary to check if intersection has been performed correctly. It can be done by calling the IsDone() method.

The results of intersection are the intersection lines and points.
