Simplification method and device for 3D model, electronic equipment and storage medium

Abstract

The embodiment of the invention provides a simplification method and device for a 3D model, electronic equipment and a storage medium. The method comprises the steps: obtaining model data of the 3D model to be simplified; for each vertex to be simplified, obtaining a reference vertex of the vertex to be simplified; obtaining the simplification times of the to-be-simplified vertex and each reference vertex of the to-be-simplified vertex; calculating the area of each target triangle; for each vertex to be simplified, judging whether preset simplification times and area conditions are met or not;if yes, deleting the to-be-simplified vertex in the to-be-simplified 3D model and each target triangle corresponding to the to-be-simplified vertex; newly building a triangle formed by two target reference vertexes and any remaining reference vertex in the to-be-simplified 3D model; and updating the simplification times of each reference vertex, and updating the to-be-simplified 3D model. By adopting the method, the model driving equipment with limited computing power can perform model rendering and other operations on the 3D model.

Description

technical field [0001] The invention relates to the technical field of computer graphics, in particular to a simplified method, device, electronic equipment and storage medium for 3D models. Background technique [0002] With the development of computer graphics, 3D (threedimensional, three-dimensional graphics) technology has made great progress in many fields. At present, 3D models expressed in the form of triangular meshes in 3D technology are relatively common, such as figure 1 as shown, figure 1 The model 110 in is a 3D model formed by splicing many triangles. [0003] However, the current 3D model has too many triangular faces, and the 3D model is too complex, which leads to a huge amount of calculation for rendering the 3D model and performing operations such as motion driving. The problem of excessive calculation due to the complexity of the 3D model will make it difficult for model-driven devices with limited computing power to perform model rendering and action-...

Problems solved by technology

[0003] However, the current 3D model has too many triangular faces and the 3D model is too complex, which leads to a huge amount of calculation for rendering the 3D model and driving the action.

The problem of excessive calculation due to the complexity of the 3D model will make it difficult for model-driven devices with limited computing power to perform model rendering and action-driven operations on the current 3D model. It is too high to meet some application scenarios with real-time requirements
