Research on Optimization Technology of Three Dimensional Model

摘要

Method of reconstruction and model simplification are two key optimization technologies for three dimensional model, there are several problems in these methods, such as, low time consume, bad interface and accuracy problem. Firstly, existing methods and implementation toolkits related with our research are introduced. Secondly, a modified reconstruction algorithm based on Voronoi diagram is proposed. Thirdly, a new algorithm of semi-automatic mesh simplification is presented with the aim of simplifying error correction and achieving higher efficiency. Finally, two tests are implemented to prove that our new methods can improve the efficiency of reconstruction and has a good visualization performance.
