三角形面片 meaning in English

tri patch

Geometry continuity of the triangular facets is analyzed in the course of generating stl files . the index relation is built up between every triangular facet by making use of this continuity
通过分析stl转化过程中三角形面片之间的几何连续性，应用其连续性，使得各个三角形之间建立一种索引关系。
Abstract : the tolerance and generation of the stair - error in rp were studied . by using the normal vector information of the tringon facets in stl file , a calaculating method of stair - error was proposed and a slice - adapt algorithm which will save the time of mold manufacturing was presented
文摘:研究了快速成型过程中阶梯误差的产生与度量，并利用stl文件中的三角形面片的法矢量信息给出了阶梯误差的计算方法，提出了可变分层厚度的算法，采用自适应分层来减少成型时间的方案
