You probably want to do SLERP, i.e. Spherical Linear intERPolation.
Search for slerp and animation i Google and you will find tons of
lecture notes going through the algorithm, and probably also several
free software packages.
I'm not much of a Performer expert so I can't tell if native Performer
can help you with this, but I'm sure someone else can.
