Basically. You have to store indices while counting if you don't want to overcount. This is the part he glosses over.</blockquote></div><br><div>No, he has structure implicitly through the mesh. The mesh overcounts some points, but if you can easily determine how much it overcounts, then you have an efficient way to compute a non-redundant count.
