MeshFix

This software takes as input a polygon mesh and produces a copy of the input where all the occurrences of a specific set of "defects" are corrected. MeshFix has been designed to correct typical flaws present in RAW DIGITIZED mesh models, thus it might fail or produce coarse results if run on other sorts of input meshes (e.g. tessellated CAD models). When the software fails, it appends a textual description to the file "meshfix.log". The input is assumed to represent a single CLOSED SOLID OBJECT, thus the output will be a SINGLE WATERTIGHT TRIANGLE MESH bounding a polyhedron. All the singularities, self-intersections and degenerate elements are removed from the input, while regions of the surface without defects are left unmodified.本软件以多边形网格（polygon mesh）作为输入，可生成输入网格的修正副本，其中所有特定类型的“缺陷”均会被修复。MeshFix 专为修复原始数字化（RAW DIGITIZED）网格模型中的典型缺陷而设计，若将其应用于其他类型的输入网格（例如镶嵌化计算机辅助设计（CAD）模型），则可能出现运行失败或生成粗糙结果的情况。当软件运行失败时，会将失败原因的文本描述追加写入至"meshfix.log"文件中。本软件默认输入为单个封闭实体对象（CLOSED SOLID OBJECT），因此输出将为单个包裹多面体的水密三角形网格（WATERTIGHT TRIANGLE MESH）。输入中的所有奇异点、自相交与退化图元均会被移除，而无缺陷的表面区域将保持原样。

背景概述

MeshFix是一个用于修复多边形网格缺陷的软件工具，特别针对原始数字化网格模型，能够去除自相交、奇异点和退化元素，输出单一水密三角形网格。它适用于单个封闭实体对象，并包含相关文档和开源代码链接。
