I'm glad to hear that the utility stuff is working well.
As far as the triangulation, you're right. My mesh class
does only the simplest (worst) triangulation of the data
points--it uses all of them! For large numbers of points,
interactivity is shot. A better solution would be to use
a mesh decimation technique to reduce the number of triangles
generated. I haven't checked around, but there may be some
Java code to do this out there on the net somewhere.
