An Improved Algorithm Based on Incremental Insertion in Delaunay Triangulation

Target position is a critical step in the process of constructing Delaunay triangulation. This paper establishes an improved incremental insertion method which realizes fast location based on moving center of gravity along the search direction. It is effective to solve unstable searching path problem usually occurring in some special cases, such as the line from target point to current center of gravity passes through a vertex of a triangle or coincides with a triangle edge. Simulation results show that there exists only location path using this method and the constructing efficiency is increased.
