Translations:Aeroplane/36/ro

Right, back to work. Change Yaw to 45° and Pitch to -30°. Click on OK to show that the operation has been completed. Now get back the Placement Task and look at the Rotation box. It has reverted to 'Rotation axis with angle' and has some wierd numbers Axis and Angle boxes. Mine had Axis: (0.219493,-0.529904,0.819161) and Angle: 53.65°. The three numbers in brackets are the XYZ components of a unit vector in the 3D space. It is the axis about which our original Aeroplane was rotated to get our final Aeroplane. The angle is how much it was rotated. Clever, huh, but not very friendly! It was Euler who showed that you could combine a series of XYZ rotations into one rotation about one axis.
