Method and system for simplification of 3D model

Abstract

The present application discloses a method for simplifying a 3D model, the method comprising: calculating the weight value of the vertex according to the contribution degree of the vertex to the outline of the 3D model; generating clustering units centered on the vertex; wherein, the clustering The higher the weight value of the vertex where the center of the class unit is located, the higher the priority of the clustering unit; it is judged in turn according to the order of priority from high to low whether there are clustering units other than the center. other vertices; if they exist, transfer all the information of the other vertices in the clustering unit except the center to the vertices corresponding to the center; this method can take into account the visual effect of the three-dimensional model texture Simplify the three-dimensional model; the application also discloses a system for simplifying the three-dimensional model, a computer-readable storage medium and a terminal, which have the above beneficial effects.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and system for simplifying a three-dimensional model, a computer-readable storage medium and a terminal. 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 model simplification starts from the geometric simplification of the 3D model and does not involve the preservation of the texture. However, the texture is an import...

Problems solved by technology

However, the texture is an important feature of the visual effect of the model. If the texture cannot be kept intact, if it is disordered, the visual effect of the model is difficult to meet the actual engineering requirements.
