Embodiment Construction
[0036] The present invention will be further described below in conjunction with the accompanying drawings.
[0037] The triangular mesh construction method of the present invention is mainly realized by computer software, and is realized through the following steps:
[0038] Input: a point set V that is not completely collinear on a plane, and a preset value h of the side length;
[0039] Output: line set E and triangle set T that meet the conditions of the Delaunay triangular mesh;
[0040] Pre-processing: as attached figure 1 As shown, calculate the geometric center v of the point set V c ,Such as figure 1 -As shown in (1), calculate each point in the point set to v c to form a point-to-center distance set (V, D), and sort the point distance set to obtain the sorted point distance set (V, D s ), and concentrate the point distance on the first three points (v 1 , v 2 , v 3 ) to construct initial triangle t 1 ,Such as figure 1 -shown in (2). If the center point v ...
