Abstract:7We 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.
