Dear Cgal users,

I am trying to mesh a 3D segmented image using as domain oracle a « Labeled_image_mesh_domain_3 ».

The mesh is very nice, except close to the image surface where the mesh does not really conform to the image boundary (see attached picture).

Is there a way to enforce that the final mesh of tetrahedra entirely fills the image domain (as all labels are >0)? This is of particular importance for me since I have to apply non-trivial boundary conditions on the FE simulation that comes next.

I have tried tuning the meshing parameters but this will only reduce quantitatively this problem, and I a looking for a way to have a mesh where the outer faces coincide "almost exactly » with the image boundary.

Thank you for your advices.

Regards,

Adrien.
