Method and system for simplifying three-dimensional model

Abstract

This invention discloses a method for simplifying a three-dimensional model. The method includes the steps that a weight value of a vertex is calculated according to the degree of contribution of thevertex to the contour of the three-dimensional model; a clustering unit is generated with the vertex as the center, wherein, the higher the weight value of the vertex where the center of the clustering unit is located, the higher the priority of the clustering unit; the judgment of the presence or absence of other vertexes other than the center in the clustering unit is performed in the order of priority from high to low; and if there are other vertexes, all the information of the other vertexes other than the center in the clustering unit is transferred to the vertex corresponding to the center. According to this method, the three-dimensional model is simplified on the premise of considering the visual effects of the texture of the three-dimensional model. This invention also discloses asystem for simplifying the three-dimensional model, a computer readable storage medium and a terminal, which all have the above advantages.

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.
