We present an approach for approximate collision handling which uses probabilistic information for improving the calculated collision response between objects in real-time physically based animation. The system uses an interruptible collision detection mechanism, which checks for intersections between successive levels of a bounding volume hierarchy (BVH). Traditionally, when the collision dete...

Spring-mass systems are widely used in computer animation to model soft objects. Although the systems can be numerically solved either by explicit methods or implicit methods, it has been difficult to obtain stable results from explicit methods. This paper describes detailed discussion on stabilizing explicit methods in spring-mass simulation. The simulation procedures are modeled as a linear d...

In this paper, we address the problem of designing and implementing low-cost yet effective user interfaces for interactive computer games that heavily use physically-based animation. Due to the nature of a physics-driven gaming setup in our system, we require that the interfaces should mimic the tangibility of real-world interfaces to maximize the playability of the game. Our prototype gaming s...

In this paper, potential synthesis techniques for mammalian vocalisation sound effects are analysed. Physically-inspired synthesis models are devised based on human speech synthesis techniques and research into the biology of a mammalian vocal system. The benefits and challenges of physically-inspired synthesis models are assessed alongside a signal-based alternative which recreates the percept...

Computer-aided medical technologies such as simulators for surgical training and planning require accurate representation of soft tissue behavior under large deformations. Limited datasets, and unrealistic models for soft tissues currently hinder the advancement of surgical simulation. This work identifies the nonlinear mechanical response of liver through the development of a physically-based ...
