Abstract
Physically realistic simulations are increasingly being used in interactive environments such as surgical simulation, rehabilitation training and computer games. Such interactive environments, which are by definition real-time, demand numerical simulation of various physical modalities, collision handling, topology modifications and multi-sensory (visual, auditory and haptic) interactions with a very high degree of realism. An ideal candidate algorithm for such applications would have to be numerically efficient, highly scalable on modern CPU/GPU hardware and robust. Multilevel algorithms are known to have theoretically optimal computational performance and are shown to scale well with hardware capabilities. However, incorporating topology changes and collision constraints with these algorithms to make them viable for real-time applications is challenging. In this thesis we address these issues by presenting algorithms to efficiently incorporate constraints and topology changes within a multilevel framework for interactive simulations.
