Message:

orxonox/trunk: more optimizations of the Quaternion Class.
Now the 3D-rotation is much faster through this code:

Vector tmpRot = this→getAbsDir().getSpacialAxis();
glRotatef (this→getAbsDir().getSpacialAxisAngle(), tmpRot.x, tmpRot.y, tmpRot.z );

instead of the old Matrix-approach. furthermore glRotate is optimized much better in openGL as is clearly stated in the red book

also implemented some other really useless functions for Quaternion
