Research and design of common components for virtual scene

The development of virtual scene involves too many object; however, in most cases they share some common parts. After researching the modeling method of sky and terrain, one basic framework of virtual scene´s development is put forward. The framework covers both the modeling and rendering technique of sky and terrain, and any operation on camera. Detailed design is presented in relative section, by operating the view matrix different rotation or translation on camera is realized. On the basis of analyze various methods of sky rendering, plane is adopted to model the sky and take fish-eye picture as texture. Terrain is simulated by height map and one algorithm applying to compute the height of different position in terrain is presented. Experiment shows that this framework can improve the efficiency of Virtual Environment Development and possesses good versatility and scalability.
