Excellent! Thank you!

Yes, I had to do that -- jmol froze my browser. I haven't had a chance
yet to debug that problem, nor to experiment with parameters. But
threejs unfortunately appears to ignore the orientation parameter, which
defeats the purpose. And is there a way to disable the perspective view?
I want the 2d-view seen from above to look like a 2d vector field, with
the arrows sitting exactly on top of each other; the perspective tries
to show them all. Again, I haven't had a chance yet myself to debug or
explore parameters...
Thanks again,
Tevian
