To compute a data value based on position,
a = Mark("positions");
b = Compute(sqrt(a.0**2+a.1**2+a.2**2));
Now do your AutoColor and Image.

Never mind about the GLX. I figured that out. Had to enable it in
XFree86. And thank you Nils! But I still have a question or two.
Sorry
if this sounds dumb but is getting late and my brain is tired.
The supplied file "newfoo.net" from Nils colors nicely along the Z
axis. But I am still needing to color outward spherically from a mid
point at X,Y,Z = 0,0,0 rather than linearly along Z.
It's 03:32 hours now and I think I'll give up for the night and go at
it again tomorrow. Whoever has further advice, I'd be very pleased to
receive it.
TIA,
Gan
