Study on real-time simulation technology of large-scale virtual scene

Real-time simulation technologies of a large-scale virtual scene are studied. Besides the building of LOD models (including terrain and cultural features) based on a viewpoint in the Peking Olympic Games Planning Regions as a demonstration area, we adopt Active Surface Definition, a real-time framework, to manage the terrain data, apply ClipTexture to manage the high-resolution textures efficiently, and utilize parallel processing technology to deploy the scene data dynamically, which result in higher fidelity and better simulation effects in the virtual scene we finally build up.
