<p>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.</p>

<p>This is the simplest setup one can use with <a class="el" href="structPxBroadPhaseType.html#ac7422f895533bff02d0043d35a2b7ddaabe0a5c309436a84e58c227c548fa17da" title="Multi box pruning. ">PxBroadPhaseType::eMBP</a>. A more sophisticated setup would try to cover the game world with a non-uniform set of regions (i.e. not just a grid).</p>
