In the mesh structure of 3D models, there is a kind of situation that can make many 3D algorithms useless or even break down. Because the default input model for many 3D algorithms is a manifold structure. But sometimes we get a data that is not manifold. The left side Read more…
Each simple triangle in the mesh structure of the 3D model has three verticesThe order of the three vertices is clockwise or counterclockwise.In general, all cell vertices on a model are in the same order.If it is not consistent, that is to say it has both clockwise and counterclockwise orders, Read more…
There are many magical properties in matrix computation, such as: AB != BA A != 0, B != 0, but maybe AB = 0. AB = AC, A != 0, but we can’t get that B = C. People couldn’t understand why it was so different from ordinary numerical calculations Read more…
