Abstract

The present application discloses a method for simplifying a three-dimensional model. The method includes: calculating the first weight value of all vertices according to the characteristic degree of the vertices of the three-dimensional model; The weight value of is set as the first weight value of the boundary vertices; calculate the mesh area of ​​the corresponding associated triangular mesh of all vertices, and set the result of multiplying the first weight value of each vertex by the mesh area as each The second weight value corresponding to the vertex; select the vertex to be simplified in order according to the second weight value from small to large, and move the adjacency relationship of the vertex to be simplified to the adjacent edge vertex. This method can ensure that the edge deformation is not caused and the mesh effect is optimized during the process of simplifying the three-dimensional model. The application also discloses a three-dimensional model simplification system, a computer-readable storage medium and a three-dimensional model simplification device, which have the above beneficial effects.

Description

technical field [0001] The invention relates to the field of three-dimensional modeling, in particular to a method and system for simplifying a three-dimensional model, a computer-readable storage medium and a device for simplifying a three-dimensional model. Background technique [0002] 3D model data is the data basis for virtual reality and 3D simulation. With the development of modeling technology and the improvement of 3D application level, the accuracy of 3D models has been gradually improved. The growth of data brings about a decrease in scheduling efficiency and an increase in rendering pressure. It is a commonly used method to reduce the amount of rendered data by simplifying the model, obtaining model data with different levels of detail, and satisfying the presentation of data under different display requirements. [0003] In the prior art, the simplification of the model starts from the geometric simplification of the 3D model, without considering the simplific...
