What do you exactly mean by magnification. Isn't that just zooming in really far in to the object would mean just move the camera close up. If you want a part of the screen to be zoomed in, you would have to render to a texture, then draw a circular area of that texture onto the frame buffer.

When I read your code I can't really figure out what you are trying to do. Commenting would really help. I do however see that you are using immediate rendering functions (glBegin and glEnd). You should also consider learning about VBO's, which is the more 'modern' and the more common way of doing things.

sorry for the late reply 

yes i mean zoom in / out .
the reason why there is no comment because my comment still in Indonesian language and i still working to make the English one.

my lecturer teach me using glBegin and glEnd, so i don't know what is VBO, can you give simple explanation about VBO ?
