; iRigidBody* CreateRigidBody(iFrame* o) : Creates a RigidBody and associates it with the active PhysicsScene coordinator. This function accepts an <code>iFrame* o</code> parameter. This parameter can be NULL if desired but should usually be the address of a valid iFrame. <br/><br/>The passed iFrame will be bound to this RigidBody. Every frame, PhysicsScene will update the frame's homogenous transformation matrix (T) to follow the location and rotation of the RigidBody. This is done at the end of the physics update step.
