Hi I am using CGAL for producing a Constrained triangulation in 2d. At
some point in my program, I need to remove vertices. I use
dt.remove(fh->vertex(li)) Most of the times it works, but there are some
cases where apparently the triangulation becomes invalid.
Do you mean that triangulion.is_valid() returns false?
Are you sure that the face_handle you are using is valid (i.e. points to a face that is in the triangulation)?


Sebastien.

Attached are
two images. The first shows a mesh. I want to remove the vertice inside
green triangle (which is not part of the mesh, only the others are) When
I remove the vertex 9, the triangulation becomes invalid Note that
vertice 82 is inside a triangle ?? this should not happen. Can anyone
help? Thanks Miguel
