Detailed Description

This is the interface for the dynamics core.

It handles all bookkeeping for rigid bodies and joints. It also handles collision response. Collision detection is done in another plugin.

Main creators of instances implementing this interface:

iDynamicSystem::CreateSystem()

Main ways to get pointers to this interface:

iDynamicSystem::FindSystem()
