Method, device, medium and equipment for generating model profile grid with holes in real time

Abstract

The invention relates to a method for generating a model profile grid with holes in real time, and the method comprises the following steps: extracting triangular data in a model, and constructing a BVH acceleration structure; performing model cutting based on the subdivision plane, extracting cross section data, and preprocessing the cross section data; constructing a sparse quadtree by using the processed cross section data; recursively traversing the sparse quadtree, and judging the crossing condition of a quadtree leaf node N and the model by using a BVH acceleration structure; traversing the sparse quadtree, performing profile triangularization according to the intersection condition, and obtaining a triangle vertex set Vs and a triangle serial number set Is; and generating a grid model in the three-dimensional engine based on the triangle vertex set Vs and the triangle sequence number set Is. According to the method, on the basis of accurate triangularization of discrete points by the directed distance field, real-time ground plane subdivision of any model is supported, the grids of the section are automatically generated, and subdivision is more flexible. The invention further relates to a device for generating the model profile grid with the holes in real time, a storage medium and equipment.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method, device, storage medium and equipment for generating a grid with holes in a model section in real time. Background technique [0002] In the visualization system, it is often necessary to use the display of the model section effect to display the real physical structure inside the model and the operating status of the physical components inside the equipment. However, in the traditional production process, modelers are required to make section models specially, and the finished section models are cumbersome to modify, not real-time, and the section display is not flexible enough. [0003] Therefore, there is an urgent need in this field to develop a method that can quickly generate model profiles.
