  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.
