title: How to draw smooth line in OpenGL with antialiasing?
body: <p>I need to draw a smooth line in OpenGL and here is what I have done:</p>
  
  <pre><code>glEnable( GL_LINE_SMOOTH );
  glEnable( GL_POLYGON_SMOOTH );
  glHint( GL_LINE_SMOOTH_HINT, GL_NICEST );
  glHint( GL_POLYGON_SMOOTH_HINT, GL_NICEST );
  glBegin( GL_LINE_STRIP );
      for( UINT uiPoint = 0; uiPoint &lt; iNumPoints; ++uiPoint )
      {
          const Coord &amp;Node = vecPoints[uiPoint];
          glVertex3f( Node.x, Node.y, Node.z );
      }
  glEnd();
  </code></pre>
  
  <p>What else I can do?</p>
