title: Smooth lines in OpenGL
body: <p>I'm trying to a draw a more-or-less smooth multi-segment line in OpenGL. However I find that if the line is over a thickness about 3 then the joins between the segments are not seamless. They sometimes have gaps between them. Is there a good way of making these joins smooth and gapless? I'm looking for something like the equivalent of BasicStroke.JOIN_MITER in Java.</p>
