In order to scientifically analyze the coal mining subsidence prediction, OpenGL technology is used to solve mining subsidence prediction model of the 3d visualization problem in this paper. By combining the mining subsidence theory and 3d visualization technology, the mining subsidence 3d model is established with using various coal parameters, geological features, and sample point prediction sinking...
With the development of computer technology and geological modeling study of the gradual maturity, 3D for the engineering geological modeling and information visualization analysis system of opportunities and challenges brought about. Have carried on the detailed introduction to the three dimensional geological modeling tool and the method. Summarized the three dimensional geological modeling basic...
The paper according to the actual situation of tunnels establishes six models, line tunnel, curve tunnel, link tunnel, vertical tunnel, trigeminal tunnel and binary tunnel based on tunnel midline, designs a general data structure for different section, and the corresponding algorithm of the acquisition for cross-section data of six kinds of model based on the section method. Finally, author implements...
To improve effectiveness of simulation training of equipment decontamination, it's essential to emulate and process interactions in virtual scenes accurately, wishing to produce the same results as in reality. So we firstly build mathematical and attribute models for simulation targets, and then propose a processing algorithm based on those models to dispose various interactions and mark down critical...
In order to overcome the shortcomings of the traditional three-dimensional panoramic system that it can only obtain virtual three-dimensional experience at a certain point, this paper proposed an algorithm to generate panoramic image at any point based on the hexahedral model and sphere model. In accordance with the special rules, this algorithm maps the panoramic image generated by splicing the fish-eye...
