    "abstract": "Motivated by existing models used for soft body simulation which are rather\ncomplex to implement, we present a novel technique which is based on simple\nlaws of physics and gives high quality results in real-time. We base the\nimplementation on simple thermodynamics laws and use the Clausius-Clapeyron\nstate equation for pressure calculation. In addition, this provides us with a\npressure force that is accumulated into a force accumulator of a 3D mesh object\nby using an existing spring-mass engine. Finally after integration of Newtons\nsecond law we obtain the behavior of a soft body with fixed or non-fixed air\npressure inside of it.",
