A robot path-planning method based on triangulation tracing is proposed to deal with high complication and low security in traditional path-planning method based on Voronoi diagram. An optimum path of the robot is produced by tracing the value-points of triangulation,which is combined with Dijkatra algorithm. This method doesn't need to restructure the triangulation along with the motion of obstacles,...
One extended cell partitioning algorithm is proposed for improving the efficiency of extracting isosurface. A "ring" shape zone is constructed near isosurface. The bound threshold of the zone is determined by the half length of the cell diagonal. The cells inside the zone are processed, and the cells outside the zone are removed. The fast visualization algorithm is applied to the implicit...
