/**
\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
