一种针对飞行模拟的动态地形绘制误差判断方法
A Terrain Rendering Method with Dynamic Error Metric for Flight Simulation
摘要
Abstract
In view of the requirement of flight simulation, we presented a large-scale terrain rendering method with dynamic error metric, which is based on restricted quad-tree. By means of error saturation, the error metric of our method meets the requirements of parallel computing that can be used to select terrain grid points, which makes the error metric and triangulation executed by GPU. It improves the rending efficiency of image hardware, and saves the running time of CPU. The algorithm can be used for real-time rendering of large scale terrain in high-speed flight simulation.关键词
