This time i’m going to talk about the basic components that make up a physics engine and how to put them together; this tutorial is aimed at programmers who have a basic grasp of maths and geometry but would like to step into the world of simulation.
It is my hope that if, at the beginning of this article, you are able to code the physics behind the 1972 game Pong, by the end of the article you will be equally happy writing your own constraints to use in your own physics solver!
Very nice introduction to programming physics engines.
