Hello everyone,

I'm currently working on a CGAL - VTK project aiming to create labeled 
tetrahedral mesh (.vtk) from a labeled image (.inr).

My program meshes the given image with specified parameters:
C3t3 c3t3 = CGAL::make_mesh_3<C3t3>(domain, criteria);
and then I convert it to vtk, add the scalars to the vtk mesh (points and 
cells) and save it to .vtk.

I'm testing this program with two spheres with different labels which 
intersect.
The program works but the labels on the intersection of the two spheres are 
strange... (see im1)

I tried to understand the labeling method used by CGAL but I'm not sure about 
it.
I think, according to im2, that you do not use the vertex label to label the 
cell, do you ?
Therefore, what is the labeling method of CGAL and is there a way to chose 
another strategy ?

Thank you very much,

Kind regards,
