Not really sure what you mean by "discrete regions", but here's how you convert vertice data from local positions to world positions

You would do something like this:

(Pseudo code)

vertices = meshFilter.mesh.vertices;

for (i; loop in vertices) {
    vertices[i] = transform.TransformPoint (vertices[i]);
}

//Ta Daa! You've got world coordinates

Of course there are slightly faster ways to do this, like using Transform.LocalToWorldMatrix but this is by far the easiest way.
