title: How games with infinite world deal with finite variables
body: <p>When I was missing around with Unity once, I encountered a problem where the main player's position start losing precision, wobbling and 
  movement smoothness turns into jitter.</p>
  
  <p>It turns out I was going too far off the origin point which is too much for unity's vector3 floating point to handle.</p>
  
  <p>In graphic. You can easily overcome this issue by just looping through a certain range. Ignoring that will result in an issue similar to this:</p>

  <p>Which makes me really wounder, how do developers over come finite variables to create infinite worlds. I personally haven't dipped my toes in making infinite world but I have encountered the graphic floating point error. </p>
  
  <p>If developers relay on the fact that players will never reach the point where that error start to occur then technically, it's not an infinite world.</p>
  
  <p>I would love to hear from the experts.</p>
