\brief PMap data structure for mesh collision detection.

Used by the functions NxCreatePMap and NxReleasePMap.

This structure can be assigned to NxTriangleMeshDesc::pmap or passed to NxTriangleMesh::loadPMap().

Example:

\include NxPMap_Create.cpp

<b>Platform:</b>
\li PC SW: Yes
\li PPU  : No
\li PS3  : Yes
\li XB360: Yes

	\brief Creates a PMap from a triangle mesh.
	
	A PMap is an optional data structure which makes mesh-mesh collision 
	detection more robust at the cost of higher	memory consumption.
	
	This structure can then be assigned to NxTriangleMeshDesc::pmap or passed to NxTriangleMesh::loadPMap().

	You may wish to store the PMap on disk (just write the above data block to a file of your choice) after
	computing it because the creation process can be quite expensive. Then you won't have to create it the next time
	you need it.

	\param[out] pmap Used to store details of the created PMap.
	\param[in] mesh Mesh to create PMap from.
	\param[in] density The density(resolution) of the PMap.
	\param[in] outputStream User supplied interface for reporting errors and displaying messages(see #NxUserOutputStream)

	<b>Platform:</b>
	\li PC SW: Yes
	\li PPU  : No
	\li PS3  : Yes
	\li XB360: Yes

	@see NxPMap NxTriangleMesh.loadPMap() NxConvexShape.loadPMap() NxReleasePMap

	You should not call this on PMap data you have loaded from
