I think that the problem is "what are x, y and z axis ?". When you calculate rotations around x, y, z, is it x, y and z of the rotated object ? or x, y and z of its "parent" (e.g. the room ?) ? In soya, rotate_x() is relative to the parent's coordinate system, and turn_x is relative to the object own coord syst. Other rotation could be performed using more complex rotations functions.
