Abstract

While a large amount of work is geared towards multi-resolution modeling and rendering, the presented methods work almost exclusively with static models and scenes. The ASLOD (Animated Smooth Level Of Detail) approach presented in this paper is capable of rendering animated scenes consisting of mixtures of conventional and multi-resolution models. It features coarse view-dependent multi-resolution rendering by a consistent decomposition of large models into arbitrary regions together with an analytic solution to optimize polygon allocation to such assemblies of multi-resolution models. The multi-resolution model can be used together with animated hierarchical scene graphs. Finally, the multi-resolution model can be combined with a hierarchical skeleton and a real-time deformation algorithm for animating organic shapes rendered at any desired level of detail.
