METHOD FOR SIMPLIFYING A SOURCE MESH, TAKING INTO ACCOUNT THE LOCAL CURVATURE AND THE LOCAL GEOMETRY, AND CORRESPONDING USES

摘要

The invention concerns a method for simplifying a source mesh M formed by a plurality of surfaces defined by vertices, faces and orientations thereon, said method comprising a decimation step by merging the edges, which consists in associating with an edge to be decimated, defined by two apices, a single vertex, so as to obtain a simplified mesh M', said method comprising a step which consists in selecting one edge merger among all the possible edge mergers, taking into account: at least an information representing the locally defined dynamic geography.
