QMatrix

[Gopala Krishna]

Hello,
Can someone help in learning the math behind QMatrix ? All I've been doing till now is modifying the example code found in docs and trying to fit it to mine.
My objectives to learn are:

• Learn the fundamentals first
• Learn about combining different matrices to produce nice effects
• Some advanced usage

Actually I've gone through the documentation but couldn't grasp it completely. I still sometimes get confused while applying them. Also I'd like to know some advanced operations. So please help me.

(BTW, a wiki article would be awesome )
Thanks in advance

There are three basic mapping operations:
- Translation
- Rotation
- Scaling

More complex operations are obtained when combining the above three basic operations.
Look at:
