Read the attached file (in Logo language - using it with 3impact OOP API for
Delphi) that implements Turtle (self-relative) navigation. 3impact uses ODE
under the hood, so it plays too with quaternions

also can read some postings on 3impact forum (public) on how to get such
angles (a guy making a flight simulator was asking), but I couldn't make the
code posted there work as I expected, that's why I wrote the attached one
myself (with lots of experimentation)
