But I do not want to go from the outside into a model, so simply use the code to generate a good. Use a clumsy method to set the vertices and triangles of the mesh yourself. The key code is as follows. 2. Because each of our primitives here is 1%, there may be 20.5% of such data in the proportion of a fan page, which requires special handling. 3. The last
