A Real-Time Extensible Hybrid Occlusion-Intensive Terrain Rendering Algorithm

摘要：

Real-time rendering of complex terrain, which is often used to meet the demand of the high fidelity of the virtual battlefield environments simulation, geographic information system (CIS), virtual reality (VR) and 3D games, has attracted growing interest at home and abroad over the last decades. In this paper, a hybrid terrain rendering algorithm combining multiresolution terrain rendering and occlusion culling is analyzed, a terrain simulation loop which integrates multi-resolution terrain modeling and terrain occlusion culling based on the least square plane is proposed. The algorithm based on this method not only decreases the number of polygons sending to the graphics rendering pipeline efficiently, but also takes into account of the performance optimization and its extension for dynamic terrain. By implementing the algorithm and analyzing the results from experiments, we conclude that this algorithm is valid and applicable to complex occlusion-intensive terrain rendering system.
