What does Degrees of Freedom Physics Engine mean?
DEFINITIONS: (from Wikipedia) Degrees of freedom is a general term used in explaining dependence on parameters and implying the possibility of counting the number of those parameters. In mathematical terms, the degrees of freedom are the dimensions of a phase space. Physics Engine is a computer program that simulates physics models, using variables such as mass, velocity, friction, and wind resistance. It can simulate and predict effects under different conditions that would approximate what happens in real life or in a fantasy world. Its main uses are in scientific simulation and in video games. There are generally two classes of physics engines, real-time and high-precision. High-precision physics engines require more processing power to calculate very precise physics and are usually used by scientists, commercial simulation software and computer animated movies. In video games, consumer level simuation or other forms of interactive computing, the physics engine simplifies its calcul
