海量数据纹理三维视景仿真方法研究

Research on 3D Scene Simulation Based on Massive Texture Data

无人机模拟训练系统的视景仿真部分是三维可视化的典型应用。为了达到良好的视觉效果,本文采用了大数据量的航片作为地表纹理进行贴图,研究了动态调用海量数据以避免内存耗尽的方法。以VC++为开发平台,利用OpenGL图形库,在PC机上实现了实时交互和动态漫游,达到了良好的仿真效果。

Scene simulation of the UAV simulative training system is a typical application of 3D visualization. This paper takes aerial photograph with massive texture data as the ground surface texture to get more actually vision. The method of dynamically transferring massive data to avoid ESM exhausted was analyzed, and the real-time interconnection and dynamic roaming were run based on VC ＋ ＋ platform by using OpenGL on PC.
