The Physics 3D and Physics 2D Areas

There are two different Physics Areas, one for 3D physics (Nvidia's PhysX) and another for the 2D physics system (Box2D). This Area provides various physics statistics, such as Rigidbody, Collider, and Contact counts.

The Breakdown View for each Physics Area provides some rudimentary insight into the subsystem’s inner workings, but we can get further insight by exploring the Physics Debugger, which we will introduce in Chapter 5, Faster Physics.
