MeshPatch Class Reference

Detailed Description

Generates the triangulation of a single surface.

MeshPatch is a triangular mesh patch which stores both parametric (u,v) and spatial coordinates (x,y,z). It is used as an intermediate object to compute surface-surface intersections and to generate patch meshes which are later postprocessed and merged by PatchMerger.

Deprecated:

#include <meshpatch.h>
