Hi Håkan, Relative to what? If you want it relative to the +Z axis, then use atan2(zdir.x, zdir.z), being careful to put in a special case where the camera is looking straight up or down. But I suggest you be a bit more specific with your question. For general 2D and 3D maths questions, you could do worse than look at: mathworld.wolfram.com or a slew of other 3D maths sites. -JD ______________________________________________________________________ This email has been scanned by the MessageLabs Email Security System.
