摘　　要：针对VR建模对三维模型网格数量少、网格简化算法运行快的要求,对渐进网格算法进行研究优化,提出了一种新的网格简化算法。本算法基于边塌缩和二次误差测度方法,引入三角形正则度优化简化误差,并进行边界优化。实验结果表明算法运行效率显著提升,能够较好地保证模型简化质量。In order to meet the requirements of VR modeling for a small number of 3D models and fast mesh simplification algorithm,a new mesh simplification algorithm was proposed based on the research and optimization of progressive mesh algorithm.Based on the edge collapse and quadratic error measure method,this algorithm introduces triangle regularity optimization to simplify the error and optimize the boundary.The experimental result shows that the efficiency of the proposed algorithm is significantly improved,and the quality of model simplification is better guaranteed.
