3D models in computers are classified based on geometric characteristics. They can be divided into three types: box models, surface models, and solid models. If an object is classified by the method of representation, the entity model can be divided into three categories: Decomposition representation, constructive solid geometry, and boundary representation.Common decomposition methods include: quadtree, octotree, multi-tree, BSP Tree, and so on.M
