void TGLFaceSet::EnforceTriangles | ( | ) |
Use GLU tesselator to replace all polygons with N > 3 with triangles.
After this call polygon descriptions are changed. New vertices are not expected – exception is thrown if this is requested by the triangulator. Support for adding of new vertices can be provided.

Set state of static flag EnforceTriangles.
When this is set, all tesselations will be automatically converted into triangle-only meshes. This is needed to export TGeo shapes and CSG meshes to external triangle-mesh libraries that can not handle arbitrary polygons.
