| Abstract: | The development process and steps of 3D GIS Visualization Dynamic Simulation System of Mining Subsidence are discussed in detail in this paper.Three-dimensional dynamic display of mining subsidence data in three-dimensional coordinate system is achieved based on visual c＋＋ platform by using technology of cache switch of OpenGL and ADO database programming.It also improves data processing and graphics refresh rate by double-buffering and display list functionality. |
