Abstract

The invention is suitable for the field of geometric modeling and provides a fitting optimization method of triangular mesh data and a system for achieving the fitting optimization method. The fitting optimization method comprises the steps of: A, fitting a shape function according to shape characteristics of a three-dimensional model area selected on the original three-dimensional model; B, generating an optimized fitting triangular mesh according to the shape function; and C, splicing the fitting triangular mesh back into a triangular mesh of the original three-dimensional model. According to the fitting optimization method, the selected three-dimensional model area can be subjected to the fitting optimization.

Description

technical field [0001] The invention relates to the field of geometric modeling, in particular to a method and system for fitting and optimizing triangular grid data. Background technique [0002] Three-dimensional geometric models are divided into three types: wireframe model, surface model and solid model, among which surface model is the most widely used, and triangular mesh data is a common form of surface model. The existing geometric modeling software FreeForm and Auto 123D provide three-dimensional geometric modeling functions, but users need to manually outline the trajectory and expected shape of the modeling. The disadvantages of this method are: [0003] 1) The smoothing and optimization effect cannot be achieved, and the topological correctness of the 3D model cannot be guaranteed. [0004] 2) It cannot handle the case where there are holes on the surface. [0005] 3) Repeated processing for complex protrusions and depressions. [0006] The patent application ...
