基于OpenGL的三维散乱点生成真实感地形的研究

A Study on Generating Realistic Terrain Image with 3D Discrete Points Based on OpenGL

三维真实感图形是科学可视化、计算机动画和虚拟现实的技术核心 ,也是时空一体化地理信息系统的关键技术 ,而OpenGL又是最新的三维图形的国际标准 ,为实现地形的真实感显示 ,本文讨论三维散乱点数据通过插值算法生成数字高程地表模型 (DEM) 。

A 3D realistic image is a core technique of the scientific visualization and virtural reality, and an important technique of spatio-tempral GIS.OpenGL is the current international standard of 3D image.This article discusses the implementing method of creating digital elevation model (DEM) with the discrete 3D points ,and the technique of texture mapping based on OpenGL to genarate realistic terrian.
