[RESOLVED] Does localToGlobal work with z coordinate?

Hey there.
I've got a carousel that holds images and rotates on its vertical (Y) axis (like a merry-go-round).
I need to depth sort the images while the whole carousel rotates. My problem is, as it's the whole carousel that rotates, the individual images' x and z coordinates do not change. I need some way of extracting each image's Z coordinate relative to the stage to find which is nearest. There doesn't appear to be a 3D version of localToGlobal, but is there a way to use it to extract a Z coordinate? Or is there another way to do this?
Here's the main class:

Code:

---

package {
        import flash.display.MovieClip;
        import flash.events.*;
        import flash.geom.Point;

        public class DocumentClass extends MovieClip {
                var count:int;
                const numberOfPictures:int = 7;
                const holderRadius:int = 480;
                var pictureHolder:PictureHolder;
               
                public function DocumentClass():void {
                        pictureHolder = new PictureHolder(numberOfPictures,holderRadius);
                        pictureHolder.x = 350;
                        pictureHolder.y = 200;
                        pictureHolder.z = holderRadius;
                        addChild(pictureHolder);
                        stage.addEventListener(Event.ENTER_FRAME, updateRotation);
                };
                public function updateRotation(e:Event):void {
                        pictureHolder.rotationY +=1;
                        // depth sorting code needs to go here!
                        for (count=0;count<=numberOfPictures-1;count++) {
                                pictureHolder.pictures[count].rotationY -=1;
                        };
                };
        };
};

---

The PictureHolder class just instantiates a number of RotatingImages, which themselves have methods for positioning themselves in a circle, dependent on the carousel's radius and their number in the sequence.

Any help appreciated!
Cheers.

I'm still not 100% this will work, but I've just stumbled across 'local3DToGlobal' which carries all three coordinates from a Vector3D. That should do the trick. Sweet.
