title: glRotate(angle,x,y,z), what is x,y,z in this case?
body: <p>I've read the documentation here: <a href="http://www.opengl.org/sdk/docs/man2/xhtml/glRotate.xml">http://www.opengl.org/sdk/docs/man2/xhtml/glRotate.xml</a></p>
  
  <p>It specifies that angle is in degrees.  It says that X,Y,Z are vectors.  If I say glRotate(2,1,0,0) that says I will rotate 2 degrees about the X axis.</p>
  
  <p>What happens if I say glRotate(2,0.5,0,0) and glRotate(2,0.0174524,0,0)</p>
  
  <p>I don't understand what's really happening in that situation, can someone help explain to me?</p>
  
  <p>Does it rotate as a percentage of the angle?</p>
