摘要:3D visualization is a Key Technology in CyberCity. It has been applied in many fields. In this paper, we discussed and studied several key techniques of 3D visualization in CyberCity. These key techniques contain Oriented Object 3D Data Model, Advanced Modeling Techniques which contain Particle System and Billboard, 3D Scene Accelerate Rendering Techniques, Information Inquire techniques in 3D scene and so on. The 3D Scene Accelerate Rendering Techniques contain Object Culling, Back Face Culling and LOD (level of detail) technique. Based on these techniques, we designed and implemented an advanced 3D Render ing Engine. At the end of paper, we give some results created by the 3D Rendering Engine. The results show that the 3D engine can r ender highly reality 3D scene and user can obtain highly immersion by rambling in 3D scene and inquiring information based on database
