We introduce a spatial index to support the fast retrieval of large neighborhoods of points on a polygonal mesh. Our spatial index can be computed efficiently off-line, introducing a negligible overhead over a standard indexed data structure. In retrieving neighborhoods of points on-line, we achieve a speed-up of about one order of magnitude with respect to(More)
We present a method to compute a measure of karate movement quality from MoCap data. We start from well-known common assumptions: an expert athlete is able to perform movements characterized by stable and clean postures and stances, i.e., he is able to conclude the movements without hesitation, noisy small fluctuations or movement ripples. To explore this(More)
