Abstract :
In flight simulation, scenes are rich in content with the characteristic of large-scale. In this paper, a large-scale terrain rendering procedure suitable for flight simulation is given and a terrain data pre-scheduling criteria is established. A linked queue based quadtree partitioning algorithm is proposed, so that triangulation and elimination of cracks can be performed simultaneously during the process of quadtree partitioning. Finally an experimental system is designed and implemented to perform large-scale terrain real-time rendering. Based on this system, we studied the key technologies of real-time rendering large-scale terrain. Experimental results show that the system is suitable for real-time rendering large-scale terrain.
