[vtkusers] matrix rotation "jumps"

[Andrew Maclean]

What you are seeing is probably correct behavior. I suspect you are
experiencing the dreaded "gimbal-lock".

for a solution, look at:
"Real-Time Rendering"; T. Akenine-Möller, Eric Haines; 2ndEdn, A.K.Peters
Ltd.
In particular 3.3.2 Quaternions, Rotation from one vector to another. 

This may give you a way of doing it.
