It should work for any face based on the 3 vertices, not sure though since I didn't write it.
Just took a quick look at it and the method should work for any face object. For a sphere though it has a different function entirely. intersectBoundingRadius(pos:Number3D, radius:Number):Boolean Maybe not so good to test with a sphere and try a cube instead?
