In the frame of project GOODSHAPE (ERC Starting Grant, ERC-StG-205693), we continued developping new algorithms for discretizing 3D objects with an optimum sampling. We generalized the notion of Centroidal Voronoi Tesselation to the Lp metric, and devised a fully automatic hex-dominant meshing algorithm [15] (Figure 5 ). We filed a patent FR 10/02920 (filed 07/09/10). To efficiently compute the Voronoi diagrams used by the method, we developped efficient algorithms in 2D [16] and 3D [25] . We also proposed a new segmentation method [20] .

We co-published a book on geometry processing [26] and co-organized a SIGGRAPH course on spectral mesh processing [22] .
