Hi Yuan, You can do this by extending two classes (assuming you are using Java3D for Displays): visad/java3d/DefaultDisplayRendererJ3D.java visad/java3d/MouseBehaviorJ3D.java The extension of DefaultDisplayRendererJ3D would override createSceneGraph, that would differ from DefaultDisplayRendererJ3D.createSceneGraph in that it constructs the extension of MouseBehaviorJ3D rather than MouseBehaviorJ3D. The extension of MouseBehaviorJ3D would override processStimulus, that would scan the AWTEvents in its 'Enumeration criteria' argument looking for MouseEvents, then invoke 'super.processStimulus(criteria)' to let MouseBehaviorJ3D.processStimulus do its work. Please let me know if you have problems. Cheers, Bill ---------------------------------------------------------- Bill Hibbard, SSEC, 1225 W.
