Visualization Modeling of Mine Roadway Based on DirectX

摘要

Digital mining (DM) is the information model, 3D visualization modeling of roadway is an application of DM and occupies a very important position in DMpsilas construction. In 3D visualization roadway , people can get its 3D graphic and know the engineering change accurately in time, and itpsilas helpful for showing the spatial relationships of excavation engineering and orebody, wall rock even the surface diggings. Take Dongtan mine of Shandong as example, this paper mainly research the data processing - arithmetic, modeling method and visualization analyses of roadway based on DirectX 9.0C. That is builds every regular roadway according to the key points of it to realize 3D roadway modeling through the process of point rarr line rarr face rarr single roadway rarr multi-roadway. Finally through combined with the technology of texture mapping and light setting, the author modeling the roadway and do some spatial analyses also.
