【Abstract】 D acceleration of real time graphics rendering is very important in Virtual Reality applications. Levels of Detail(LOD) are used in most complex rendering system. A simple, fast, and effective polygon reduction algorithm based on edge collapse is presented in this paper, which utilizes the “minimal cost” method to calculate a set of LOD, to get real time rendering of 3D virtual environment.更多还原
