- * @defgroup collide Collision Detection
- *
- * ODE has two main components: a dynamics simulation engine and a collision
- * detection engine. The collision engine is given information about the
- * shape of each body. At each time step it figures out which bodies touch
- * each other and passes the resulting contact point information to the user.
- * The user in turn creates contact joints between bodies.
- *
- * Using ODE's collision detection is optional - an alternative collision
- * detection system can be used as long as it can supply the right kinds of
- * contact information.
