Virtual Reality Complex Scene Generation, To Simplify And Optimize The Technology Research

Virtual reality has been widely used in the fields such as distance learning, virtual shopping, electric power system, flying simulation, digital earth, etc. These application need only realism complex Virtual Environment, but require the user can interact with the virtual scene at interaction frame rate. Virtual reality communities and other visualizations have always faced the problem that their "desirable" visualization dataset sizes are one or more orders of magnitude larger than what the hardware can display at interactive rates. Thus we need resolve the problem by attempts to bridge the gap between the complex scene and the real-time rendering.This article gives an interview for the method of complex scene generation and fast rendering. Then make a detailed presentation for several items about model simplification of multiple levels of detail model. At last, the paper introduce an practical illustration to resolve the contradiction between the complex scene and real-time rendering.
