I'm trying to create a really simple viewer that will allow the user to zoom in or rotate the object in the viewer. After I did the rotate behavior I tested it and it worked fine. Then I tried to do the zoom behavior and ran into a few exceptions. After I fixed it so no more exceptions were occurring I tested it again this time to see that when I hit an arrow key the viewer just blanked out. I don't know why this is happening, although I suspect that it has something to do with how or when I'm adding things into the scene graph. Please help me out here I'm new to java3d. The entire code is listed at http://www.csupomona.edu/~elberry/page/java/code.htm Please take a look. Any help would be greatly appreciated.
