Hi all,

I am getting familiar with CGAL recently and I have some questions on 3D Mesh generation package:

Q1. Is it possible to generate a volumetric tetrahedral mesh from triangulated surface, but having the surface triangles not changed, only tetrahedral elements inside the volume remeshed.

Q2. When I use the mesh_3D_image example for finer mesh resolution (0.3 mm - facet size and cell size) , I get the mesh with jagged boundaries (see the fig attached), and

 if I want to have smoother mesh I do give larger facet_distance to have low approximation, but still I have the same problem of jagged boundaries.

Q3. For generating meshes from the segmented image, Is it possible to control the parameters (facet_size,cell_size, etc) for each segmented region individually?

I thank you a lot in advance to help me with these questions.

Cheers.

Jatin
