ParSys: a new particle system for the introduction of on-line physical behaviour to three-dimensional synthetic objects

The incorporation of physical behaviour to synthetic objects constructed by computer is one of the main objectives of computer graphics research. In this paper we present a new interactive deformable model based on linked volumes. As such, it is straightforward and implicitly preserves the volume of the modelled objects. The proposed model resorts to Lennard-Jones potential fields for the representation of the internal energy stored in the deformable objects. Experimental results show that this new deformable model can simulate the physical behaviour of elastic volumetric objects both in a realistic and interactive way.
