一种基于不平滑度的网格简化算法
Mesh simplification algorithm based on non-smoothness.
摘要
Abstract
In three-dimensional modeling, a 3D mesh model often contains hundreds of millions of triangular facets, which cause a lot of inconvenience to the storage of the model as well as the drawing, rendering, transmission and interactive process-ing of it. This paper proposes a triangle collapsing method, which calculates each vertex’s degree of non-smoothness, deter-mines the weight of each triangle surface and the new vertex’s location and cumulative non-smoothness after a triangle surface is deleted based on the non-smoothness of its three vertices, this paper proves that the method can maintain the geometric charac-teristics in a good way while simplifying a mesh by instance of verification.关键词
