面三角 meaning in Chinese

facial triangle

Secondly , the triangle meshing of contour loops that includes triangle plane filling between layers and section triangle plotting was accomplished
其次,边界轮廓环的三角网格化:层间三角面片填充和端面三角划分。
In triangle plane filling between layers , the loop matching operator between layers was adopted , which is that the loops were matched according to their characters , geometry centers and perimeters . four kinds of regular algorithm in filling between layers were analyzed , and the shortest diagonal algorithm , which was rather fit to this dissertation , was adopted in this dissertation . the contour loops of section were grouped and each loop was split to make each loop become a single outer loop that was triangle split with delaunay algorithm
在层间三角面片填充方面,采用层间轮廓环按环的性质、几何中心和周长进行匹配的层间匹配算法;分析了层间三角面片填充的四种常用的算法,并根据本文需要选用并实现了最小对角线法;端面三角划分时,将端面的轮廓环进行分组,再对每组环进行切分处理,使得每组环变成一个单一的外环,对单一的外环按delaunay算法进行三角划分;将所生成的三角面片按规定的格式写入stl文件,生成可直接为快速原型制造所接受的stl文件格式。
