Abstract

The invention discloses a three-dimensional geometrical discretization processing system. The system comprises: a geometrical surface reading and storing module used for carrying out data storage on geometric surface information of a three-dimensional grid model; the geometric ridge reading and storing module that is used for carrying out data storage on ridge information of the three-dimensionalgrid model; the triangular patch vertex acquisition module that is used for performing data storage on the vertex of each triangular patch by reading the information of each surface in the model; andthe triangular patch vertex and ridge position relationship judgment module that is used for judging the position relationship between three vertexes and ridges of each triangular patch. According tothe three-dimensional geometric discretization processing system disclosed by the invention, the grid data is rapidly extracted in a rapid and efficient iteration mode, internal data storage is carried out only on the corresponding data, data extraction efficiency and simplification are achieved, the utilization rate of the internal data is greatly increased, redundant storage of the data is reduced, and the processing speed of computer functions such as three-dimensional model view display or mesh generation is increased.

Description

Technical field: [0001] The invention relates to a computer-aided design system for three-dimensional model view display and grid division. Background technique: [0002] With the continuous maturity and improvement of modern product design and analysis methods such as Computer Aided Engineering (CAE) and computer simulation analysis system, 3D models are being used more and more.
