Implementation method for improving digital-analog simplification effect of digital factory

Abstract

The invention belongs to the technical field of model processing, and particularly relates to an implementation method for improving the digital-analog simplification effect of a digital factory. The method comprises the following steps: acquiring an overall model, and carrying out data reorganization on partial models; wherein a part of models divide grid data according to the same material, merge the grid data of the same material, and remove redundant vertexes existing in the grid data, so that the grid model is divided into a plurality of module parts; and respectively simplifying each grid of the partial model by adopting a grid simplification technology, and simplifying the overall model and the partial model by adopting a self-adaptive mode. According to the method, the partial models are divided according to the same materials, the grid data of the same materials are combined, each part is simplified by adopting a grid simplification technology, and different reduction proportions are automatically distributed according to different numbers of patches of each part during simplification; therefore, the damage caused by excessive reduction on the part with a small number of the surface pieces by adopting the same reduction proportion is avoided.

Description

technical field [0001] The invention belongs to the technical field of model processing, and in particular relates to an implementation method for improving the digital-analog simplification effect of a digital factory. Background technique [0002] With the continuous development and application of computer technology, a large number of component models under computer-aided design contain rich geometric information, which not only makes the model sufficiently detailed and realistic, but also increases the computational pressure of model rendering and simulation. Since a large number of geometric details are unnecessary in the simulation scene, so-called lightweighting of these models is required. [0003] Since most of the digital models are represented by triangular meshes, the lightweight is the simplification of the triangular meshes. In theory, all existing triangular mesh simplification techniques can be used for lightweight attempts. Generally speaking, the mesh sim...
