There are two kinds of Euler angles:

1) Fixed coordinate space -- EVIL!

2) Moving coordinate space -- not that evil, but fairly expensive to 
compute with.

When people say "Euler Angles" they seldom qualify which version, just 
like when people talk about matrices, they seldom qualify whether they 
use row vectors or column vectors. I guess everyone just assumes that 
everyone else uses whatever convention they happen to be using.

Cheers,
