outline showing through other objects

[GoogleCodeExporter]

What steps will reproduce the problem?
1. view = new View3D({x:250,y:200, renderer:Renderer.CORRECT_Z_ORDER}); 
2. cube.outline = outlineMaterial;
(see example code provided below)

What is the expected output? What do you see instead?
You'd expect the outline to not show of objects that are positioned completely 
behind other objects. Instead the outline is showing through other objects.

What version of the product are you using? On what operating system?
3.6. Windows xp.

Please provide any additional information below.
Here is example code of the bug:

package {
    import away3d.containers.View3D;
    import away3d.materials.WireframeMaterial;
    import away3d.primitives.Cube;
    import away3d.core.render.Renderer;

    import flash.display.Sprite;

    [SWF(width="500", height="400", frameRate="60", backgroundColor="#FFFFFF")]
    public class BugExample extends Sprite
    {
        public var view:View3D;
        private var cube:Cube;
        private var cube2:Cube;

        public function BugExample()
        {
            view = new View3D({x:250,y:200, renderer:Renderer.CORRECT_Z_ORDER});
            addChild(view);

            cube = new Cube();
            cube2 = new Cube();

            var outlineMaterial:WireframeMaterial = new WireframeMaterial(0x000000);
            outlineMaterial.thickness = 3;
            //cube.outline = outlineMaterial;
            cube2.outline = outlineMaterial;

            cube.z = -300;

            view.scene.addChild(cube);
            view.scene.addChild(cube2);

            view.render();
        }

    }
}

Hi I used to have the same problem. It seems that in revision 2786 the guys 
changed a little bit getUVT method in ViewSourceObject.
Changing back the return result in line 303 from return new Vector3D(0, 0, 
(_da/_v0z + _db/_v1z) / _det); to return new Vector3D(0, 0, (_da*_v0z + 
_db*_v1z) / _det); did the job for me. I hope this will help you.
