利用计算几何的相关算法，把矢量数据的节点和边界线作为TIN网三角形的端点和边，对TIN网的局部进行三角化。

Utilizing related algorithms of computational geometry to triangulate TIN partly to make node and line as vertex and side of triangles.

So again, if we think about that shape of that carbon atom, it's going to be trigonal planar, 120° it's going to have bond angles of 120 degrees, because we have this set up of having three hybrid orbitals.

如果我们考虑碳原子的形状，它是平面三角形，键角是，因为我们有这三个杂化轨道。
