FollowCam view for vehicle

[Carbon Philter]

Hi again, scripting gurus.
Is anyone an expert with the Dan Linden FollowCam settings and could help me?

I've been trying all sorts of permutations with the variables for a while now and am beginning to think that what I want to achieve can't be done, but I'd be more than happy to be proved wrong.
For a vehicle - ship - being driven, I can happily get any number of views tracking movement from behind, ranging from the worm view below to overhead, but I'm trying to get a sideview and also a rearview and haven't yet been able to achieve it, even with the rearview_cam parameters in the script from the Wiki
.
Having looked at the way the spin cam works I'm coming round to thinking that the only way to get a continuous side/rear facing view would be to replace the 'for' statement with a timer and constantly updating the camera position by using llGetPos()  and adding the appropriate local offset and rotation to it. Here's the spin_cam parameters I was thinking of using as a starting point:

spin_cam()
{
    llSetCameraParams([
        CAMERA_ACTIVE, 1, // 1 is active, 0 is inactive
        CAMERA_BEHINDNESS_ANGLE, 180.0, // (0 to 180) degrees
        CAMERA_BEHINDNESS_LAG, 0.5, // (0 to 3) seconds
        //CAMERA_DISTANCE, 10.0, // ( 0.5 to 10) meters
        //CAMERA_FOCUS, <0.0,0.0,5.0>, // region relative position
        CAMERA_FOCUS_LAG, 0.05 , // (0 to 3) seconds
        CAMERA_FOCUS_LOCKED, FALSE, // (TRUE or FALSE)
        CAMERA_FOCUS_THRESHOLD, 0.0, // (0 to 4) meters
        CAMERA_PITCH, 30.0, // (-45 to 80) degrees
        //CAMERA_POSITION, <0.0,0.0,0.0>, // region relative position
        CAMERA_POSITION_LAG, 0.0, // (0 to 3) seconds
        CAMERA_POSITION_LOCKED, FALSE, // (TRUE or FALSE)
        CAMERA_POSITION_THRESHOLD, 0.0, // (0 to 4) meters
        CAMERA_FOCUS_OFFSET, <0.0,0.0,0.0> // <-10,-10,-10> to <10,10,10> meters
    ]);
 
    float i;
    vector camera_position;
    for (i=0; i< 2*TWO_PI; i+=.0125)
    {
        camera_position = llGetPos() + <0.0, 14.0, 0.0> * llEuler2Rot(<0.0, 0.0, i>);
        llSetCameraParams([CAMERA_POSITION, camera_position]);
    }

 
Am I missing something fundamental or are my attempts to achieve these other views doomed to failure and I will have to simply resort to overriding the normal camera view using Ctrl/Alt/LMB?

Thanks
Carbon

 check these?...  you can change the vectors to move the cam & focus ?

  llSetCameraEyeOffset(<0.0, 0.0, 0.0> );
  llSetCameraAtOffset(<0.0, 0.0, 0.0> );

Sorry i am new to these cam controls can you change them to such a way that you can make it stay over your head kind of like zelda games ?

[Xiija]

something like ...

 llSetCameraEyeOffset(<-8.0, -0.00, 2.0> );
       llSetCameraAtOffset(<3.0, 0.0, 2.0> );

Thx for suggestions.

I've used them in the past when fixing a specific view.

I'll try them but they relate to one-off camera settings rather than the params which allow you to change camera on the fly. According to the wiki - http://wiki.secondlife.com/wiki/LlSetCameraParams - these particular settings do not appear.

Hey ho, back to more experimenting!
