Hi, I’m quite new here so please if this has already been asked dont flame me .
Anyway I was wondering, how would I set up the OpenGL projection matrix so that I can pass a set of coordinates to it and expect them to be in roughly the same position no matter what resolution is on the screen: 640x480, 800x600, 1024x768, etc. If this is not possible please let me know, I thank you in advance.
