unit sphere

Convex modulus depicted overall degree of convexity of the unit sphere of spaces. It was very different for degree of convexity of each point that it would produce very great influence on the whole feature of the spaces.

凸性模刻划了空间单位球面的总体凸性程度，但是每一点的凸性程度都有很大的不同，这将会对空间的整体性质产生很大影响。

At the same time, by subdividing an icosahedron and projecting all its vertices onto the unit sphere from the center, we can get a spherical triangle mesh with subdivision topology.

然后，将一个正多面体进行细分并将每一次细分所产生的新顶点投影到单位球面上，如此生成一个细分网格。
