◆ AddedPoints()

std::vector< Base::Vector3f > AbstractPolygonTriangulator::AddedPoints ( ) const

The triangulation algorithm may create new points when calling Triangulate().

This method returns these added points.

Note: : Make sure to have called PostProcessing() before using this method if you want the surface points the new points are lying on.

Usually the created faces use the indices of the polygon points from [0, n].

If the faces should be appended to an existing mesh they may need to be reindexed from the calling instance. However, there may other algorithms that directly use the indices of the mesh and thus do not need to be touched afterwards. In this case the method should be reimplemented to return false.
