Hi all,
I am trying to fill a hole in Polyhedron with Polyhedron_incremental_builder. The code I implemented sometimes works
and sometimes not. It is very weird. I used ABSOLUTE_INDEXING mode. All facets on the polyhedron are triangles.
The triangles to fill the hole are known. I used add_facet() to insert a new facet after checking by test_facet(). Sometimes I got the error message like:
CGAL::Polyhedron_incremental_builder_3<HDS>::
lookup_halfedge(): input error: facet 2231 has a self intersection at vertex 473
This means add_facet() fails although test_facet() succeeds. What does this message really mean? How can a triangle intersect itself?
Thanks,
Mengda
