++ \brief Creates regions for PxSceneDesc, from a global box.
++
++ This helper simply subdivides the given global box into a 2D grid of smaller boxes. Each one of those smaller boxes
++ is a region of interest for the broadphase. There are nbSubdiv*nbSubdiv regions in the 2D grid. The function does not
++ subdivide along the given up axis.
++
++ This is the simplest setup one can use with PxBroadPhaseType::eMBP. A more sophisticated setup would try to cover
++ the game world with a non-uniform set of regions (i.e. not just a grid).
++
++ \param[out] regions Regions computed from the input global box
++ \param[in] globalBounds World-space box covering the game world
++ \param[in] nbSubdiv Grid subdivision level. The function will create nbSubdiv*nbSubdiv regions.
++ \param[in] upAxis Up axis (0 for X, 1 for Y, 2 for Z).
++ \return number of regions written out to the 'regions' array
++
++ \see PxSceneDesc PxBroadPhaseType
