摘　　要：研究了一类三维累进网格生成算法,在网格分辨率固定的前提下,以期获得较高质量的三维模型;基于二次误差模型,提出了基于累进网格生成的改进算法;引入了边界约束条件,提出了二阶邻域指标。实验证明,该算法输出的模型质量优于文献中的算法。A kind of progressive three-dimensional mesh generation algorithm was studied. Under the premise of a fixed resolution and to obtain a higher quality of three-dimensional model, an improved algorithm for the progressive meshes based on quadric error metric was presented. The algorithm used a contour protection and produced a 2-adjacent filed index. Experimental results indicate that the model produced by the algorithm is better than others in literature.
