[ODE] rotation

[Erick Tryzelaar]

Sure there is:

This is from David Eberly's (chief architect behind the netimmerse engine)
webpage:

http://www.magic-software.com/Documentation/EulerAngles.pdf

Also, if you're interested, the rest of that site has an amazing amount of
useful information. Its good stuff.
