override public function unproject(nX:Number, nY:Number, sZ:Number):Vector3DCalculates the scene position relative to the camera of the given normalized coordinates in screen space.
Parameters
nX:Number — The normalised x coordinate in screen space, -1 corresponds to the left edge of the viewport, 1 to the right.
| |
nY:Number — The normalised y coordinate in screen space, -1 corresponds to the top edge of the viewport, 1 to the bottom.
| |
sZ:Number — The z coordinate in screen space, representing the distance into the screen.
|
Vector3D — The scene position relative to the camera of the given screen coordinates.
