[JAVA3D] Attribute change performance Issue.

[Norihito Hiruma]

Hi All. I am developer of CAD-Application. Right now, I am trying Java3D but Java3D's attribute change performance is too bad. The color change of 2500 Attributes takes about six seconds. [CPU:PentiumIII Xeon 550MHz(single processor) Memory:256MB GA:Visualize-fx4+] Java3D can't be used for CAD-Application in such performance. Is my coding improper? Or, is this a limit of Java3D? A source code is attached. Can anyone of you help me, please? Note: In CAD-Application, there is much operation of changing entity color at a time. And CAD-Entity must hold a respectively different attribute. So, every Shape3D has different Attribute-Node and change all. Regards <<Test.java>>
