3D Visualization Calculation And Research On Dynamic Simulation Of Landslide Based On Open GL

In the course of landslide research, a lot of the information related to the three dimensional space and position are involved, such as the geological information, location information and landslide shape etc. In general, all these information appear in the form of statements and2D graphics, they can not give a person an intuitive impression. In this way, it is difficult to make full use of these information and grasp these information when it is necessary to integrate the information, and it is impossible to analyze the their applicable effects for the arrangement and construction when making the virtual engineering design with the3D space. In this paper, the3D visualization software for the landslide is successfully developed with the Open GL software for building the landslide model, managing the landslide data, calculating the stability and conducting the3D dynamic simulation to solve the problems of the landslide prediction and dynamic simulation. Research conclusions:(1)Using the Open GL to make the secondary development can successfully calculate the landslide stability and realize the dynamic simulation of the sliding process of the landslide according to the calculation results, with the simple, easy, practical and scientific process.(2)By using the3D terrain model of the landslide spatial form and the3D landslide section model, the functions of the mapping, storing and outputting of the topographic maps, sectional drawing and drilling data and connecting sliding surface etc can be realized, and it provides the rapid means for the stability evaluation and engineering design.(3)This study result is available for the dynamic3D visualization simulation and stability calculation of landslide.(4) Through the project example trial showed that in the same condition, the calculation results with the existing resultsare almost the same, can think of program calculation result is correct.
