Probing for Surface Mesh Generation through Delaunay Refinement

Résumé : Surface mesh generation through Delaunay refinement is considered as a relevant alternative to the common marching cubes algorithm. One distinctive feature lies into the fact that it interleaves shape probing (through intersection with Voronoi edges) with refinement. The current implementations require seeding the refinement procedure for each connected component so as to guarantee that all components are properly discovered by the mesh refinement procedure. This task is often left to the user. Although this is an easy task for input polyhedral surfaces, it is not when the input surface is defined as an isovalue of an implicit function. In this report we propose an automatic seeding procedure which interleaves refinement, seeding and initialization steps with the qualities of the refinement and the guarantees of careful seeding.
