3D Texture-Mapped Rectangle with a Billboard behavior

[aRTx]

Write a Java 3D program that shows a texture-mapped rectangle with a Billboard behavior. Use an OrbitBehavior object to allow view manipulations through mouse operations.

Much luck with this. Please post the results of your program here when you've finished it so that we can check it out.

pls if you can do that:
Write a Java 3D program that shows a texture-mapped rectangle with a Billboard behavior. Use an OrbitBehavior object to allow view manipulations through mouse operations.

Please don't shout in blue.

[aRTx]

But UNTIL now it is not solved, the code is just for reference

I look forward to finding out what billboard behaviour is, in big friendly capitals.
