Detailed Description

The btRigidBodyConstructionInfo structure provides information to create a rigid body.

Setting mass to zero creates a fixed (non-dynamic) rigid body. For dynamic objects, you can use the collision shape to approximate the local inertia tensor, otherwise use the zero vector (default argument) You can use the motion state to synchronize the world transform between physics and graphics objects. And if the motion state is provided, the rigid body will initialize its initial world transform from the motion state, m_startWorldTransform is only used when you don't provide a motion state.
