Detailed Description
The btStridingMeshInterface is the interface class for high performance generic access to triangle meshes, used in combination with btBvhTriangleMeshShape and some other collision shapes.
Using index striding of 3*sizeof(integer) it can use triangle arrays, using index striding of 1*sizeof(integer) it can handle triangle strips. It allows for sharing graphics and collision meshes. Also it provides locking/unlocking of graphics meshes that are in gpu memory.

if the number of parts is big, the performance might drop due to the innerloop switch on indextype
unlike that developers want to pass in double-precision meshes in single-precision Bullet build so disable this feature by default see patch http://code.google.com/p/bullet/issues/detail?id=213
