The Three-dimensional Visualization Simulation Of Top-coal Movement Regulation On The Base Of OpenGL

In this dissertation, we mainly research the principles of 3D visualization and application, in the rule of the roof coal moving system. At the same time, its application fields has been enlarged and its productions appear stremendously . 3D visualization technology enhances visualization to 3D space level. By the technology the real world is displayed in computer, the unseen world, the processes and the detailsare simulated.Therefore the 3D Visualization is the essence of Visualization technology.This thesis discusses the realized principle of 3D Visualization by researching graphics arithmetics, coordinate transformation, third dimension graphics display and so on, the realized route is decided by researching the processes of 3D Visualization.By lots of on-the-spot observation , the papers using VC++ and OpenGL the replace model imitate the moving process of top-coal and the moving process of the filler of falling top-coal. Studied to coal-caving pace distance, Coal-caving interval the meantime,and in proper order etc. Coal-caving parameter to influence the yield and let out rate, with the stone rate.Carry out to coal-caving model of 3D visualization to turn with random angle manifestation, the modification of the model with dynamic state renewal etc. make sure reasonable of coal-caving parameter.
