Abstract

The invention discloses a WebGL-based two-dimensional and three-dimensional combined drilling design method and system. The method comprises the following steps of establishing a WebGL standard-baseddrawing environment by using Three.js; horizontally projecting the three-dimensional ore body model and the three-dimensional drill hole through coordinate transformation; drawing an exploration lineon the horizontal projection by using Canvas, and storing the exploration line in a database; converting the exploration line in the two-dimensional space into a three-dimensional space; projecting the three-dimensional drill hole to a vertical plane where the exploration line is located through coordinate transformation; performing two-dimensional drilling design on the vertical projection by using Canvas; based on the WebGL technology, using three.js for achieving three-dimensional drilling display. The system comprises a data import module, a scheme setting and comparing module, a three-dimensional entity modeling module, a two-dimensional drilling design module and a template drawing module.

Description

technical field [0001] The present invention relates to the technical field of the Internet, and more specifically relates to a drilling design method and system based on a combination of 2D and 3D based on WebGL. Background technique [0002] For the 3D modeling and visualization of geological boreholes, related methods and technologies have been studied at home and abroad. Feng Zhidong (Research on 3D visualization technology of boreholes based on Hoops [J]) proposed a 3D visualization technology of boreholes based on Hoops. The layer rendering of 3D boreholes is performed through the Hoops engine, which shortens the modeling cycle to a certain extent; Mou Naixia (Research on 3D visualization of geological boreholes based on Multipatch [J]) et al. studied the 3D visualization of geological boreholes based on Multipatch, which improved the usability and compatibility of the system. [0003] The 3D visualization of geological boreholes has become a basic function of mainstr...
