[net.graphics] Left or right-handed?

trainor@hera.cs.ucla.edu (Vulture of Light) (10/31/86)

+ Right, right, right, right--the physics doesn't work in left, left, left!!!

+ Perhaps much of this right/left/up/down confusion is due to graphics books
  that sloppily switch all around.

+ The hardware argument has no bearing.

Since coordinates are purely conventional, it would be amazing
if physics "didn't work" when one chose a left-handed system.
Of course, if you don't distinguish between vectors and pseudo-
vectors (best done by using skew tensors, aka forms), you're
making a mistake that shows up when coordinate conventions are
switched on you; but it isn't the physics that's broken.
