Cam Controller Orbit

[Techni]

I've linked up the pitch and yaw of a cam controller to a pod controller, and the X Y Z to a GPS in the middle of my ship, however, I've noticed that it simply pivots around a point, and the zoom option only allows zooming in and not out. So I was wondering if it is possible to have the camera orbit around the point (Like vehicles in third person mode)?

Any help you can offer is appreciated.

Edit: I've already tried vector methods however my vector mathmatics is sketchy at the moment (Summer holidays will do that).

Nevermind, with thanks to a friend I found out how to do it simply, for those interested:

N@CameraOrbit
I@X Y Z Bear Elev Dist 
O@A B C Pitch Yaw


A = X + -Dist * cos(Elev) * cos(Bear)

B = Y + -Dist * cos(Elev) * sin(Bear)

C = Z + -Dist * sin(Elev)

Pitch = -Elev

Yaw = Bear

Where X Y and Z are the co-ordinates of the GPS you want to rotate around, Bearing and Elevation are from the pod controller, and Dist is the distance you want the camera to orbit at. A B and C go into X Y and Z on the cam controller respectively, Pitch and Yaw go into the cam controller likewise.

Very nice, I was looking for something like this, thanks!

Sine and cosine make a happy circle... It's easy as pi. (Sorry, had to do it, couldn't resist)

lol.

Good trig work, Gmod EVE here we come!
