Since a lot of people ask me about details of my Pressure Soft Body
model implementation I decided to write this paper. Paper contains
detailed description of how to start the simplest program for simulation
of soft bodies. Details about physics behind Pressure Soft Body Model
can be find in [1], which is available online^{1}. There paper I will show how to organize the code and write first
simple working soft body simulator.
