To solve it, secondary TIN construction was conducted to simplify the calculation mode by solving vectortriangle calculation so as to facilitate the automatic realization by computer.
For instance, it's also the square of the Euclidean norm on R2, the length of a two-dimensional vector, a part of the triangle inequality, and quite a bit more.
例如,R 2 的平方、二维向量的长度、三角不等式等都存在勾股定理。

We present a method, vector boundary advancing method, to generate unstructured triangle meshes, and prove its feasibility.
