I'm trying to build up an array of data per vertex on a Polyhedron e.g.

        vector<FT> vArray( nVertices, 0.0f);   

        Halfedge_handle he_itr = polyhedron.halfedges_begin();  

for ( Polyhedron::Facet_iterator fitr = polyhedron.facets_begin(); fitr != polyhedron.facets_end(); fitr++)

{

Halfedge_facet_circulator cir = fitr->facet_begin();

do

{

   // Get vertex index (as per subdivision tutorial)

   int i = (int) std::distance( he_itr, Halfedge_handle( cir.operator->()));

   vArray[ i] = // some Data

} 

while ( ++cir != fitr->facet_begin());

}

Here I'm calculating the vertex index as the distance of the half edge iterator from the start half edge.  

Is this correct, and why?
