Can anyone explain how to intersect a quad?  I'm sure I can figure it out
on my own, but if someone knows of some straightforward formulae, I'd be
very appreciative.

Since this is for LDraw, I've got the following situation:

Conditions:
- Four points to make a quad (or, to be simpler, 3 points to make a
  triangle).
- Two components for another point (probably X and Z, but it doesn't really
  matter which two).

Needed:
- Value for third component.

TIA for any help!
Steve
