Hm, I guess the question I should have asked is more general... Supposing
that I want to create a mesh object which has random factors incorporated
into it's shape (not necessarily that of a tree), and that the mesh is
built at run-time through a loop of some sort, how do I make sure that it
remembers where it left off with previous triangles? How do I make the
vertices coincide if I don't know what they will be?
