void PxRegisterArticulationsReducedCoordinate(physx::PxPhysics &physics)

Enables the usage of the reduced coordinate articulations feature.

This function is called automatically inside PxCreatePhysics(). On resource constrained platforms, it is possible to call PxCreateBasePhysics() and then NOT call this function to save on code memory if your application does not use reduced coordinate articulations. In this case the linker should strip out the relevant implementation code from the library. If you need to use reduced coordinate articulations but not some other optional component, you shoud call PxCreateBasePhysics() followed by this call.
