三维地形可视化仿真关键技术研究

Research on Visual 3D Terrain Simulation Technology

三维地形可视化仿真技术是虚拟现实的重要手段之一,主要研究真实感三维地形建模和三维地形可视化的实时绘制。本文对光照模型、纹理映射技术、阴影、场景的特效生成、实时消隐技术、层次细节简化技术等三维地形可视化仿真关键技术进行了分析。

Visual 3D terrain simulation technology is an important means of virtual reality, which deals with realistic 3D terrain modeling and 3D terrain visualization real-time drawing mainly. Some key technology such as illumination model,texture mapping technology, specific effect of scene and shadow and so on are analized.
