[JAVA3D] Application getting very slow....

[Ravi Goel]

Hi all,    I'm working in a project in Java3D....My project is RackEditor...which contains Glasses in it...I'm creating glasses using Java's Box object which is present Inside a TransformGroup & setting Transperancy attributes to it...The Rack which i have created is created using a class which extends Shape3D...   To place all the glass on the required position i'm using setTransform() method of the TransformGroup class...But as the number of glasses increases...System is getting very Slow while loading as well as when i'm trying to do something on it(like Zooming,Translate,Roatate..i'm using Picking behaviors for doing it)...If i want to make my application more efficient & fast what and all steps should i take...Is there any problem in the way in which i have created my Design...   Please suggest me some ideas...   Thanks Ravi
