I have a mesh (close to polygon soup) with texture coordinates. I'd like to use CGAL for various operaitons on this mesh; most specifically the Naf_polyhedron class. I can "thicken" each triangle to make sure it's manifold and acceptable as a Naf, but I don't know how to carry the texture coordinates through the operations so they are preserved for vertices, and interpolated for cut edges.

Also, a single "point" may have multiple texture coordinates, as the texture coordinate is a function of both "face" and "point."

Are there examples or documentation for how to do this? Or does CGAL not support this in a mostly-built-in fashion?

  • Could you try to improve your question, it is not easy to understand what you want. – sloriot May 11 '14 at 13:15
  • How do I use Nef_Polyhedron operations while preserving texture coordinates (parameterization) from the inputs to the outputs? For example, to implement a CSG operation on textured meshes? I'm starting to believe it can't be done. – Jon Watte May 12 '14 at 04:20
  • As I said, you should click on the "edit" button below your question, to try to improve it. – lrineau May 28 '14 at 09:05
  • I think my question is clear. What, specifically, is unclear about it? Which word is confusing? The specific problem statement is: "I don't know how to carry the texture coordinates through the operations so they are preserved for vertices, and interpolated for cut edges." – Jon Watte May 29 '14 at 15:26
