If the original poster wants to use OrbitBehavior, then ViewingPlatform has to be used, which the attached example doesn't. All subclasses of ViewPlatformBehavior use the ViewingPlatform to retrieve the TransformGroup containing the view transform. A ViewPlatformBehavior is made live by calling the setViewPlatformBehavior() method of ViewingPlatform. I suggest trying the version of OrbitBehavior that August Lammersdorf posted to this list on June 10 (ViewOrbitBehavior) -- it doesn't need a ViewingPlatform, just a reference to the TransformGroup to be modified. I think it *ought* to be possible to use a ViewPlatformBehavior and a ViewingPlatform without having to buy into the Viewer, SimpleUniverse, or ConfiguredUniverse utilities. There is, after all, a a public method setViewPlatform() in the ViewingPlatform utility class that can be called with a reference to a core Java 3D ViewPlatform class instance, so *in theory* a core Java 3D View instance could be attached to that ViewPlatform with its attachViewPlatform() method. The only consequence of this that I can see is that setNominalViewingTransform() would not have access to a Viewer from which to get the field of view, so it would assume PI/4. The problem is that there appears to be a bug with ViewingPlatform.setViewPlatform() -- it never attaches the ViewPlatform to a TransformGroup. I'll investigate this further and generate a bug report if appropriate. -- Mark Hood =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
