Image caching algorithms and strategies for real time rendering of complex virtual environments

摘要

This paper presents a study about the comparison of several methods of image cache management; image caching is a recent approach of rendering, based on the concepts of impostors and hierarchical scene subdivision, which exploits the coherence of consecutive frames in a graphic sequence. Anyway existent methods don't exploit the aspects in common with cache memory management; therefore they organize the image cache without using an optimal strategy.An implementation with variable factors and strategies is presented along with the results from the comparison of their performances.
