I've been a user of A:M for several years (versions) now- I've noticed in v9.5/10 the new driver (channel) interpolation type is quaternion- it used to be euler and that works best for simple rotates like a wheel turning or a propeller spinning. anybody know what the technical differences are between these two types and what the advantages are of quaternion?

the following is a powerpoint download so may take some time -

If that isn't technical enough I don't know what is!
