In with view.render(); I set camera.lookat(new Number3D(0,0,0));
Then from MouseEvent3D took stageX,stageY,stageZ scaled the normal of this
and tweenlite the cam x,y,z to the scaled normal x,y,z, the lookat in with
render() handles the lookat.
code snippets:
//
--------------------------------------------------------------------------------------------------------------
private function render(e:Event=null):void
{
// keep camera looking at center of sphere
camera.lookAt( new Number3D(0,0,0) );
view.render();
}
//
--------------------------------------------------------------------------------------------------------------
some code inside main.as/mxml
//
--------------------------------------------------------------------------------------------------------------
// Set location of click target primitive (not added to view)
clickTargetPrimitive.x = e.sceneX;
clickTargetPrimitive.y = e.sceneY;
clickTargetPrimitive.z = e.sceneZ;
// Set center cube to look at clickTargetPrimitive
centerCube.lookAt(clickTargetPrimitive.position);
// Tween camera to scaled face normal of clickTargetPrimitive
var camTarget:Number3D = new Number3D();
camTarget.scale(clickTargetPrimitive.position,0.3);
camTarget.add(camTarget,clickTargetPrimitive.position);
TweenLite.to( camera, 4, {
x:camTarget.x,
y:camTarget.y,
z:camTarget.z,
onComplete:rotationComplete
});
//
--------------------------------------------------------------------------------------------------------------
private function rotationComplete():void
{
// doesn't do anything once set at start of script
stage.quality = StageQuality.BEST;
}
//
