在开源数据库Postgre中使用GSQL语言实现不规则三角网中的初始三角网的建立-triangle irragular network

这是我自己写的从数据库中读出数据，并显示，并构成不规则三角网的程序，可以在程序中添加约束线。-This is written in my own读出数据from the database and displays, and triangulated irregular network constitutes the procedure, you can add a constraint in the procedure line.

构建三角网的VB程序,构建三角网的算法很多,这是逐点插入法,并在插入后进行外接圆检测-Build triangulation VB procedure, construct a triangulation algorithm is very much, this is the point insertion method, and circumcircle detection after insertion
