Abstract

The invention discloses a three-dimensional model simplification method, apparatus and device, and a computer readable storage medium, and the method comprises the steps: obtaining an original three-dimensional model, carrying out the data sampling of the original three-dimensional model, obtaining each point for carrying out the data sampling as a vertex, and obtaining the coordinate informationand texture information of each vertex; carrying out grid reconstruction based on the coordinate information and the texture information of each vertex sampled from the original three-dimensional model to obtain a corresponding grid, carrying out parametric mapping from three dimensions to two dimensions on the grid to obtain a corresponding two-dimensional model, and determining the coordinate information and the texture information of each vertex on the two-dimensional model; and constructing a new three-dimensional model as a to-be-simplified three-dimensional model based on the grid, the vertexes, the coordinate information of the vertexes on the two-dimensional model and the texture information, and simplifying the to-be-simplified three-dimensional model. Due to the fact that the three-dimensional model used for achieving simplification is the three-dimensional model with high data consistency, simplification with a large simplification proportion can be supported.

Description

technical field [0001] The present invention relates to the technical field of computer graphics, and more specifically, relates to a three-dimensional model simplification method, device, equipment and computer-readable storage medium. Background technique [0002] The 3D model is the basis of 3D simulation, and simplification of the 3D model is one of the main ways to improve the loading and rendering efficiency of the 3D platform. The existing method generally simplifies the method of eliminating the existing grid vertices and triangular meshes of the 3D model; The three-dimensional models made in different ways are all simplified according to the above methods, which may cause shape deformation and texture disorder due to excessive simplification. [0003] To sum up, the technical solution for simplification of the 3D model in the prior art has the problem that the simplification ratio is too large, which leads to the deformation of the shape and the disorder of the tex...
