I installed medit and it can open the file and it looks good. But its only showing the surface.
Which is the best tool to view this mesh files?

Thanks for your answer. It maybe what i need. However doesn't seems to work. I dont know maybe it's a bug.

I tried to use the make_mesh_3, but its not doing what it have to.

I copied the Mesh_3/mesh_implicit_sphere.cpp sample code, it compiled and runned succsessfully, however the generated mesh(or mesh file) is not valid at all. I tried to open it with gmsh, or convert it with tetgen to off, but none of them works. Tetgen finds a lot of trouble in the mesh.

Have a look to the 3D mesh generation package.
The functions make_mesh_3 and refine_mesh_3
can be tuned to remesh a triangulated surface
and mesh the interior of this surface.
Note that the gemetry of the input surface  will be preserved
but not the representing mesh: the input surface will be retriangulated.

Hi, i hope somebody can give me some advice.

I have a non convex surface what i want to triangulate in 3d.

I have the 3d points of the surface and the surface triangles.

Im able to use the triangulation with the points but i get a convex hull.

In basic what do i have to use to triangulate this object in 3d with respecting the boundaries. How do i add the surface to the triangulation? Is there any option to achive this in cgal?
