Michael, actually, I cannot remember any 3-D math class where the Z axis referred to anything but height above the X-Y ground plane. The problem, as Rick pointed out, is that most people have a few years of 2-D paint programs under their belt, where only two axes are used: X and Y, and they are parallel to your computer screen, which happens to lie vertically in the real world. I feel Impulse was totally right in using standard 3-D terminology. Blaq!
