    I am currently displaying a 3D surface...using MFC and OpenGL
    Now I want to add a zoom feature to my application.
    This is what I want to do...
    Using mouse I will draw one rectangle(i.e select the region) on the surface,I want to zoom that particular region...
    How should I do this...or what do i need ,in order to develop such kind of feature.

    Re: zoom

    why don't you move the camera to the selected region (also consider the depth,frustum, etc) ?
