|      I am open to any suggestion. I must say this post is something of
| a surprise to me. Perhaps are you referring to the lack of any
| "reasonably standard" C++ implementation of rotations in R^3?

no, I think I'm referring to  comment from Gary Powel about this issue (he 
works in the Games industry, I think)

anyway, I don't have seriuos time to investigate this issue, but maybe you 
could look at
scene graph packages like OSG to see if you can do the same:
