Hey All,
I had a specific situation where I needed to pan the hovercamera
without a limit. The current HoverCamera3d built into away3d has a pan
limit of 90 and -90, as past those limits the model would flip in a
bizarre manner.
The key method was to detect if the camera had flipped around to the
oppiste side:
public function isflipped():Boolean{
var normalTilt:Number = Math.abs(_currentTiltAngle)%360;
return (normalTilt >= 90 && normalTilt <= 270);
}
then also to set the Matrix3d orientation of the camera accordingly:
arcane override function update():void
{
var orientation : Vector3D = (isflipped())? new
Vector3D(0,1, 0) :
new Vector3D(0, -1, 0);
if (target != null){
lookAt(target.transform.matrix3D.position,orientation);
}
super.update();
}
Anyway here is the example:

and here is the source:

My trig isn't strong so it took me a while to figure out how to fix,
so I hope it helps someone else save time.
