基于OpenGL的三维地形可视化技术与实现

Visualization to 3-D Terrain Based on OpenGL and Its Implementation

介绍了OpenGL和三维地形的相关概念,详细说明了三维地形的制作以及可视化实现。利用建模技术建立了三维地形模型,在场景中使用光照、纹理映射技术,使图像具有较强真实感,并通过键盘,实现人机交互,实现了三维地形可视化。

Some related concepts about OpenGL and 3-D terrain are described,and then the process of 3-D terrain creation and visualization implementation are explained.3-D terrian model is established through modeling technique,and lighting technique is used to improve the graphics'truth in the scene,and the exchange between human and computer is realized through keyboard,and the visualization of the 3-D terrian is achieved ultimately.
