Benefits of technology

This patented technology allows create an efficient way to design a 3D object that fits into specific space shapes with minimal effort compared to traditional methods like ruler graphs. It achieves this by optimizing both gaps between adjacent points on each side of certain faces of the triangle shape while also considering its overall area size.

Problems solved by technology

The technical problem addressed by this patented method is that current methods require complicated algorithms or requires finding boundary before starting the process can result in non-synchronized mesh constructions with limited options being used optimizing their performance.

Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings.

[0037] The triangular mesh construction method of the present invention is mainly realized by computer software, and is realized through the following steps:

[0038] Input: a point set V that is not completely collinear on a plane, and a preset value h of the side length;

[0039] Output: line set E and triangle set T that meet the conditions of the Delaunay triangular mesh;

[0040] Pre-processing: as attached figure 1 As shown, calculate the geometric center v of the point set V c ,Such as figure 1 -As shown in (1), calculate each point in the point set to v c to form a point-to-center distance set (V, D), and sort the point distance set to obtain the sorted point distance set (V, D s ), and concentrate the point distance on the first three points (v 1 , v 2 , v 3 ) to construct initial triangle t 1 ,Such as figure 1 -shown in (2). If the center point v ...

Abstract

The invention provides a method for constructing a triangular grid and the application thereof in a geotechnical engineering modeling. The invention has the advantages that a triangular grid meeting the Delaunay triangle grid rule can be simply and rapidly constructed, and the grid optimization can be carried out synchronously in the method, which is applicable to the construction of a triangle grid in accordance to the Delaunay triangle rule according to a two-dimension or three-dimension space discrete point set, and can be applied to the construction of an irregular three-dimension model, such as the construction of a three-dimension stratum layer model.
