Putting It All

Together

e have now built a complete physics engine that can simulate any kind of

Wrigid body, detect collisions between objects, and realistically resolve those

collisions. It is capable of running the physics for a huge range of games, and it is time

to put it through its paces.

Before we work through the demonstration applications, it is worth taking stock

of where we are and looking at the physics engine as a whole.

17.1 Overview of the Engine

The physics engine we have built has four distinct parts:



The force generators (and torque generators) examine the current state of the

game and c alculate what forces need to be applied to ...
