Jeff:

Do you mean, how do I do manage to do things in a complicated way that
take only little more than a one-liner when done properly, as David has
just pointed out? :-(

But seriously: I guess the only "resource" is the *need* to solve a given
problem, and some very basic geometry knowledge. Like in this case: x^2 +
y^2 < r^2 defines a filled circle. No need to be a math pro for that,
thank goodness. I'm sorry, but I really can't point you to any book or web
page [1].

Cheers,
Timm

[1] Except, of course, JD Smith's dimension-juggling tutorial for IDL,
which helps you to get arrays into shape. But you know where to find that,
I hope.
