VisAD includes an algorithm that ties all the triangles together into
one strip. In general, it is pretty good at creating short strips.
However, it may do poorly on a very small set of triangles where it
can't get much running room. Of course, human common sense can look
at a small set of triangles and come up with a good arrangement in
strips, but algorithms lack common sense.
Glad your program is working.
Cheers,
Bill
