Hi all,

I need to retrieve a list of triangles from a surfaces mesh made of 
facets of 3 to more vertices.
(But facets with more than 3 vertices aren't of really in dimension 2 
because points aren't so colinear due to float precision limit.)

I try to make this triangulation on each facet separately.
But, the triangulation_3 processes tetrahedron triangulation when 
dimension=3 (so, on all facet with more than 3 vertices).
Is it possible to constraint the triangulation to get only triangles 
facet instead of tetrahedron ?

The triangulation also doesn't take into account of facet bounds as 
shown on the picture enclosed.
Is it possible to constraint the triangulation to get only triangles 
inside the facet bounds ?

I have also test with the triangulation_3 on the all mesh, bu the result 
isn't a regular triangulated mesh.


My final objective is to get a triangulated surface from a mesh to test 
it with the Mesh simplification package.
I give enclosed the VRML file of the mesh that I want to triangulate.


Best regards,
Cédric.
