Sorry I made a mistake.

Yes that's the basics of it. It does some other funny things too. For example it re-orders the indices, so if you have
0--1 6 3 | / / | | \ | / / | | \ 2 8--7 5--4
That corresponds to:
index buffer = [ 0,1, 2, 6, 7,8, 3, 4,5] adjacency = [-1,1,-1, 2,-1,0, -1,-1,1] point rep = [ 0,1, 2, 1, 4,7, 1, 7,2]
Index 5 is not replaced by 7 because the lowest index is always used. So it should have been the other way around: point rep = [ 0,1, 2, 1, 4,5, 1, 5,2]
If the indices had not been re-ordered then the point representation would have been [0,1,2, 1,7,2, 1,4,7].
And similarly [0,1,2, 1,5,2, 1,4,5].
I'll put this example into the test.
