title: What is the correct field of view angle for human eye?
body: <p>At the moment i use 45 degree angle for my gluPerspective(). Is this the correct angle to make the rendering look realistic in how humans perceive it? Also there is an issue with the window aspect ratio, for example 2:1 window will make 45 degree angle look more like 80 degree angle on a screen with 3:4 ratio etc. So the window size changes the perspective as well.</p>
  
  <p>So what is the correct window size ratio and field of view angle for making a game look most realistically compared to how humans perceive the world?</p>
