I wanted to implement Zoom Window Functionality in my C#.Net application using CSGL (OPENGL) , Zoom Window Functionality means Zooming the specific area of the drawing, Can anyone have the idea of this functionality??? I have done with the normal Zoom Functionality on mouse scroll event. Now I am not getting how to show the selected area of drawing on CSGL control after Zoom Window. Anybody know atleast which OPENGL command to use for showing selected part of graphics?
The sample example of it would help me a lot to implement the same.
Thanks & Regards,
