I am trying to calculate the tiltAngle, and panAngle of an object for the HoverController, and am not
too sure where I am going wrong:

var obj3D  : ObjectContainer3D = getMarker( id );
var r:Number        =  Math.sqrt( ( obj3D.z * obj3D.z ) + ( obj3D.y * obj3D.y ) + ( obj3D.x * obj3D.x ) )
var theta:Number    = (Math.acos(obj3D.position.y / r))/(Math.PI/180);
var phi:Number      = (Math.atan2(obj3D.position.z, obj3D.position.x))/(Math.PI/180);
   
cameraController.tiltAngle = theta;
cameraController.panAngle = phi; 

cameraController is a HoverController…

any help is appreciated


Thanks

Looks like this fixed it:

var r:Number =  Math.sqrt( ( obj3D.z * obj3D.z ) + ( obj3D.y * obj3D.y ) + ( obj3D.x * obj3D.x ) )
var theta:Number = (Math.acos(obj3D.position.y / r))/(Math.PI/180);
var phi:Number = (Math.atan2(obj3D.position.z, obj3D.position.x))/(Math.PI/180);
       
cameraController.tiltAngle = 90 - theta;
cameraController.panAngle = 90 - phi ;
