fast quadric mesh simplification原理 Fast quadric mesh simplification是一种基于二次误差度量的网格简化算法。该算法的原理是通过对网格上的顶点进行合并或删除,以减少网格的复杂度,并尽可能地保持网格的形状和细节。 算法的基本思想是使用一个二次误差度量来度量网格简化的效果。该度量将每个顶点的位置与其相邻面片的...

1、Basic Quadric Error Metric QEM(Quadric Error Metric)作为网格简化重要的度量方式,在论文Simplifying Surfaces with Color and Texture using Quadric Error Metrics详细讨论了网格包含其他属性(color, texture, normal)的处理方法,假设网格有颜色属性,考虑三角形 ,,T=(p,q,r) ,顶点 p=[px,py,pz,pr,pg,pb...
Fast-Quadric-Mesh-Simplification Summary Since I couldn't find any code that's fast, memory efficient, free and for high quality, I developed my version of the quadric based edge collapse mesh simplification method. It uses a threshold to determine which triangles to delete, which avoids sorting...
An Improved Algorithm for Mesh Simplification Based on Quadric Error Metrics 摘要:先进制造进展(英文版)Xiao-hu
使用二次曲面减少网格三角形。 这是Sven Forstmann的C ++网格简化代码的Pascal端口。 它速度快,内存效率高,免费且质量高。 它使用阈值来确定要删除的三角形,从而避免了排序,从而提高了性能,但请注意,这可能会导致质量降低。 图形用户界面可执行 这段代码已嵌入到表面渲染工具中(2016年5月5日及更高版本)。 Surf ...
