No.  It's done the same way that Sculpt does it.

There is a list of points (data type - VECTOR ie. xyz coords).

There is a list of edges.  Each edge consists of two indices into
the points list.

There is a list of faces.  Each face consists of three indices into
the edges list.

Send me mail if you have any questions.
