Hello, right now i am developing 2D Map for my 3D Environment.
I am able to do 3rd Person Camera which followed the movement of "object movement" inside my 3D environment.
My problem is i am having difficulty to put the 2D Map in circle shape and screen them in same window as the 3D environment?

Get an alpha texture with a circle in the middle. call gluOrtho2D, disable depth testing and draw a quad with your texture on it.
