Travis,
You could orthogonalise the matrix before writing it out. It's relatively easy
to make a routine that will find a 'best' rotation matrix that is perpendicular
and very close to the original. That way you don't have to deal with the up,
right etc.
I can write you a C routine to do so if you like, or send you some pseudo-code.

| (...) Thanks for the offer. It sounds like I can make use of parameters that Lars has already implemented if I just change my outputs slightly, so I think I'll go that route. If you've already got the code or pseudo-code lying around, I'd like to (...) (19 years ago, 6-Dec-05, to lugnet.cad.ray)
