pure virtual

get read and write access to a subpart of a triangle mesh this subpart has a continuous array of vertices and indices in this way the mesh can be handled as chunks of memory with striding very similar to OpenGL vertexarray support make a call to unLockVertexBase when the read and write access is finished

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

Initial value:

{
protected:
    btVector3 m_scaling

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.
