body: <p>How can I actually declare <a href="http://www.opengl.org/sdk/docs/man/xhtml/gluPerspective.xml" rel="nofollow noreferrer">gluPerspective</a>?</p>
  
  <p>I mean I am drawing a spiral and I am setting z = -50 in the beginning and looping until the circle is complete. So what will be the declaration of gluPerspective?</p>
