34///The btIDebugDraw interface class allows hooking up a debug renderer to visually debug simulations.
35///Typical use case: create a debug drawer object, and assign it to a btCollisionWorld or btDynamicsWorld using setDebugDrawer and call debugDrawWorld.
36///A class that implements the btIDebugDraw interface has to implement the drawLine method at a minimum.
