hi sir,
In my application .. mouseWheellistener  and mousemotionlistener  attached to a GLCanvas. GLCanvas is attached to the frame . if attached mouse listener i'm getting the error andfor that  i need to extends to AWT.  All the mouse events of  mouseWheellistener  and mousemotionlistener appear  to working fine ..but i'm not able to understand model view metrics and projection metrics properly .in my application i can able to render the 2D shape like Circle . i'm trying to implement the zoom operation using mouse event ...
please give some idea for transformation and Zooming operation in JOGL . I'm doing homework for this .but i din't get the solution .is there any documents related this.



Thank you.
