So I just rearranged it to be x^2 + y^2 +z^2 - r^2 = 0 for the isosurface.

Sure - It's just a thing copied from the docs.  And it only gets evaluated once
AFAIK, so I just keep it the same for recognition purposes.   But good eye.

I can.   But I like to see all the moving parts, and a function definition is
less overhead than a whole include file.   I wasn't sure what I'd be modifying
as I tweaked all the little bits in my quest.

Thanks as always for keeping a keen eye on the details.   :)
