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).
[out] | regions | Regions computed from the input global box |
[in] | globalBounds | World-space box covering the game world |
[in] | nbSubdiv | Grid subdivision level. The function will create nbSubdiv*nbSubdiv regions. |
[in] | upAxis | Up axis (0 for X, 1 for Y, 2 for Z). |
