Trying to find some info on applying quaternion rotations without using the copytopoints @orient point attribute.

I build my quaternion, and then I'm stuck on doing two things:
-Applying the rotation to an unpacked object and a packed object

I've tried the rotate by quaternion VOP with unpacked geo and the makeinstancexform for packed geo and nothing seems to work this way...
I've done some research but didn't find anything usefull (outside of copytopoints @orient).

Can some one point me in the right direction?
