Mesh repair with topology control

Participant : Franck Hétroy.

This work is done in collaboration with Carlos Andújar, Pere Brunet and Álvar Vinacua from Universitat Politecnica de Barcelona, Spain, and has been published in the CAD journal [7] . The purpose is to propose an efficient method to create 2-manifold meshes from real data, obtained as soups of polygons with combinatorial, geometrical and topological noise (see Figure 3 ). We propose to use a voxel structure called a discrete membrane and morphological operators to compute possible topologies, between which the user chooses.
