[Papervision3D] 3D >> 2D coordinates

[Makc]

in dod3d you have:

public var screen :Number3D = new Number3D();
...
private function calculateScreenCoords( camera :CameraObject3D ):void
{
	var persp:Number = (camera.focus * camera.zoom) / (camera.focus + view.n34);
	screen.x = view.n14 * persp;
	screen.y = view.n24 * persp;
	screen.z = view.n34;
}

perhaps simply changing calculateScreenCoords( to public would help.
