I made stupid mistakes, now it works, thanks to all of you. Another
question is that how do I get the normal by cross product or dot product
if I am looking from the sky to the ground, for example:

target
Thanks in advance

Maybe you should use this instead:
lookAt(new Point3d(0, 0, 0), new Point3d(0, 0, -5), new Vector3f(0, 1,
0));
Hope this helps.

Hi, thank you for replying. I tried t3d.invert() with the lookAt()
function but it still doesn't work. If I move the cube to (0, 0, -5),
it shows me the cube, but I tried to move the TranformGroup between the
BG and ViewPlatform by using lookAt(new Point3d(0, 0, 0), new Point3d(0,
-5, 0), new Vector3f(0, 1, 0)); and then use t3d.invert(); and then
tg.setTransform(t3d); but it doesn't show me anything. Any hints?
Andy
