Rotation Orders Explained

The first thing I want to mention is how to set the correct rotation order. Unfortunately this was something that I didn't understand until fairly recently, but now I know I wish to document it for future reference. So here we go...

Rotation order - The order in which the rotation axis will be documented.
The last axis in the rotation order will carry all the others with it.

For example - XYZ
The rotation of the Z axis will carry the X and Y axis with it.
The rotation of the Y axis will carry the X axis with it, but will have no effect on the Z axis.
The X axis will have no effect on anything but itself.

The important axis - the one that affects everything else - goes at the end.
The least important - the one that affects only itself - goes at the beginning.

The best way to work out which rotation order to use is to experiment. Try it out to discover which one will work best.
