It is encouraging that you took the initiative to write this journal manuscript, but it needs a lot of work as I am afraid that in its current form it is likely to be rejected. Besides the style that needs fixing, my main concern is the claim that th…

Mesh Data Structure in OpenCascade eryar@163.com 摘要Abstract:本文对网格数据结构作简要介绍,并结合使用OpenCascade中的数据结构,将网格数据在OpenSceneGraph中可视化. 关键字KeyWords:OpenCascade.OpenSceneGraph.Triangulation.Mesh Data Structure 一.引言 Introduction 三角网格就是全部由三角形组成的多边形网格.多边形和三角网格在图形学和建…

上一篇介绍了Marching Cubes算法,Marching Cubes算法是三维重建算法中的经典算法,算法主要思想是检测与等值面相交的体素单元并计算交点的坐标,然后对不同的相交情况利用查找表在体素单元内构建相应的网格拓扑关系.Marching Cubes算法简单,但是存在一些缺陷:1.模型二义性问题:2.模型特征问题. 对于二义性问题,以2D情形为例,存在一个单元中同一顶点状态而不同的连接方式(如下图所示). 图:2D中Marching Cubes算法的二义性问题 那么对于上图中两种连接方式…
