      Could you please elaborate? I did include one possible way of
linking with rotations in the library. This work did stem (in part) from
some work with rotations specifically for some 3D graphics problem
(though this part, interpolation of orientation under constraints, is
*not* included in the library).

      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?
