[JAVA3D] Adding a collision detector

[Dean Keeler]

Hi,   I am trying to add a collision detector to the parent of a shape node that is being checked for collision.  The parent is a TransformGroup.  When I run the program, it appears to add the collision detector with no errors (at least no errors are shown in the DOS window from the command line) but the virtual world will never render the vrml object.  No errors are displayed but the screen is black and no vrml object is rendered.  When I comment out the line of code that adds the collision detector to the parent, the world is rendered correctly.  I have no idea what is going on.  Can anyone help me or give some possible suggestions?   I greatly appreciate it,   Dean   P.S.  Thanks for all of your suggestions regaring my issue of orbiting the view around the object.  I'm still trying different suggestions and ideas but have not achieved 100% success yet.
