Hi,
I understand the concept of matricies, Vectors and Points in 3d Space. I have
learnt this at University.
I have an issue trying to understand the concept of OpenSceneGraphs use of Quaternions
and "attitude".
I do not really get what Attitude is, I'm used to the concepts of
Translate,Rotate,Scale thanks to learning maya.
This describes quaternions, and has lots of links to show how they
relate to other orientation representations:

This describes what we mean by "attitude":
