| The mine pit three dimensional visualization is a kind of important model technology in the digitized mine construction domain, and this technology is applied most widespread in coal mine, the realization of the coal mine shaft three dimensional visualization will help us to enhance the coal mining efficiency and the coal enterprise's management level.This article takes VC++6.0 as the developing platform, and completed the mine pit three dimensional model's building and the demonstration unified the OpenGL graphic processing software. It elaborated Delaunay the triangular net's algorithm principle, and has given Delaunay triangular net's production method as well as used the anomalous triangular net (TIN) to establish the mine pit terrain the three-dimensional model process; It elaborated how to established the mine pit industry square's three-dimensional model with the aid of 3D the MAX model's building tool, loads this model in the terrain corresponding position, and product the strong three-dimensional industry square's basic principle and realize-process in the terrain surface; It explained the basis mine shaft tunnel's traverse point data, the tunnel cross section data and the method of how to establish correspondence three dimensional tunnel model. It introduced the OpenGL's characteristic, the function and the basic work flow, and studied the method and the step of how to realize the mine pit model three dimensional visualization by using the OpenGL software. Finally, unifies the three dimensional visualization technology on shangshe-erjing coal mine's actual production, and carried on the three dimensional model's building and the model visualized demonstration to this mine pit's terrain, the industry square, and the tunnel, the application result indicated that the mine pit three dimensional visualization technology raised this ore coal production efficiency and the business management level. |
