Hi All,
I am trying to implement a refinement tool for FEM meshes using CGAL (3D mesh Generation) and VTK ( mainly for file I/O).
As part of this, I need to convert a VTK (unstructured) grid with multiple subdomains to a suitable CGAL domain on which a new 3D mesh (Mesh_complex_3_in_triangulation_3) can be created.
I managed to extract subdomain boundaries as polyhedral surface meshes (Polyhedron_3) and can create 3D meshes for each of them individually. However, what I would like to have instead is a single instance of Mesh_complex_3_in_triangulation_3 whose subdomains correspond to the domains defined by these surface meshes (closed, non-intersecting, shared boundaries).
The Mesh_3/mesh_implicit_domains.cpp example shows how to create 3D meshes from multiple implicit functions using the 'Implicit_multi_domain_to_labeling_function_wrapper'...
Is there a similar wrapper for domain creation from multiple polyhedral meshes?
Many thanks in advance!
Daniel
