Adaptive resolution in physics based virtual environments
2008 (English)In: SIGRAD 2008 Conference Proceedings, 2008Conference paper (Refereed)
We propose a systematic approach to adaptive resolution in physics based virtual environments (VEs) that combines the conventional requirements of realtime performance, visual appearance with important requirements on the physical simulation, such as accuracy and numerical robustness. In particular, we argue that adaptive resolution is a key element to achieve robustness in fixed time-step VEs. The idea is to adaptively substitute unstable subsystems with more simplified and robust models. The method is demonstrated on systems including stiff wires. The algorithm brings stability, realtime performance and preservation of the important physical invariants to the system. The application to general systems is discussed.
