[JAVA3D] works as an application but not as an applet for ImageComponent2D

[Michael Carter]

Hi Java3D: I can get my program to run as an application.  But, when I try to run it as an applet I get a null pointer exception in my ImageComponent2D. I am a newbie so I do not know where I am going wrong. What is it that I do not know? Can I get a clue?
