基于OPENGL技术的矿区沉陷三维GIS可视化动态模拟系统

3D GIS Visualization Dynamic Simulation System of Mining Subsidence Based on OPENGL Technology

本文详述了矿区沉陷三维GIS显示系统的开发过程及步骤,采用OpenGL缓存切换与ADO数据库编程技术,基于Visual c++平台实现了三维坐标系下矿区沉陷数据的三维动态显示,并运用双缓存和显示列表功能提高了数据处理效率和图形刷新速度。

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.
