Simplification method and device of three-dimensional model and storage medium

The invention relates to a three-dimensional model simplification method and device and a storage medium, and the method comprises the steps: converting a grid of a three-dimensional model into a plurality of connected graph sets, and enabling each connected graph set to comprise a plurality of connected graphs; for each connected graph, according to vertex attributes of the triangular patches in the connected graph and topological information of the triangular patches in the connected graph, determining simplified weights of triangular edges of all the triangular patches in the connected graph; in the triangular edges of all the triangular patches, the to-be-simplified edges are determined at least according to the simplification weights and the basic simplification errors of all the triangular edges, the three-dimensional model is simplified based on the to-be-simplified edges, and it can be ensured that the simplified three-dimensional model still maintains the original model topology. 本申请涉及一种三维模型的简化方法、装置和
