Hello,
I have a gray level image with multiple labels (1, 2, 3, ... ). I want to
form a surface mesh for each, such that the boundaries between labels are
aligned (e.g. what happens when running CGAL::make_mesh_3 on a domain with
multiple labels).
A similar post said to run CGAL::make_mesh_3 on the images and export them
to .off files:
http://cgal-discuss.949826.n4.nabble.com/Isosurfaces-from-Gray-level-image-td4661158.html
However, when I try this the outputs are not manifold and have to be
remeshed and many non-manifold regions have to be manually removed.
I have run the surface mesh generation on each individual label and have
gotten all manifold outputs, but the boundaries between labels are not
aligned.
Should I extract each surface from the mesh_complex_3_in_triangulation and
run polygonal mesh repair? Or is there a way to get the surface mesh
generation to mesh multiple surfaces at once?
Thanks!
