title: OpenGL - selective world rendering
body: <p>I'm building a miniature city with the basic minimum looks of a city (roads,buildings,trees etc) where u can move around. I know that rendering the whole model set in each frame doesn't work...</p>
  
  <p>So can anyone give me an insight on the standard (but easiest) procedure used in selectively rendering only the visible parts of the system? I mean, just displaying only the visible stuff (with respect to the camera position) and not rendering the unseen part.. 
  Im using VC++ and GLUT API.</p>
