Image Description, by Those two pictures show my talk at SIGRAD conference held in UMEA (Sweden) on the 20-21.11.2003. We (me and Mark Ollila) present and describe results of pressure Soft Body model. In the picture you can see a shot taken by my friend J. Kominiarczuk on the conference when I had a presentation of the results.
Publication details: Matyka, M. and Ollila, M. "A pressure model for soft body simulation", Proc. of Sigrad, Umea, November 2003,
Abstract: Motivated by existing models used for soft body simulation which are rather complex to implement, we present a novel technique which is based on simple laws of physics and gives high quality results in real-time. We base the implementation on simple thermodynamics laws and use the Clausius-Clapeyron state equation for pressure calculation. In addition, this provides us with a pressure force that is accumulated into a force accumulator of a 3D mesh object by using an existing spring-mass engine. Finally after integration of Newtons second law we obtain the behavior of a soft body with fixed or non-fixed air pressure inside of it.

I'd like to thank Mark Ollila for his help with the publication and whole SigRAD organize community for making it so interesting this year. See you next year.
