Hi to all,
OK David, your stuff makes a contour ... but you go through trigrid,
so you loose the initial resolution (a bit like going from vector to
raster graphics ...).

so MY REAL QUESTION is: what is so special about the triangle fed into
CONTOUR ??? Why can't I just provide my own??
I guess I now must turn to ITTVIS.

Why not?

you're dead on. But at least some other folks like me now know it by
reading it.

No, I use this wonderful tool:
http://www.cs.cmu.edu/~quake/triangle.html

Which is widely used for Computational Fluid Dynamics ... and it would
be nice that IDL could use this native triangle grid ...
Thanks for your patience,

Fabrice
