Hello!

This is my first programming for processing, am using it for a graduate course project. I am doing a map visualization, working with Unfolding. It relies on glgraphics, which I am having a hard time wrapping my head around (I've done a good bit of programming, none in graphics).

What I am trying to do is smooth a line (and in the future 2D circles) using glgraphics. I've ended up with this example which I thought would work, and while it draws a line, it doesn't smooth it.

1. import processing.opengl.*;
   import codeanticode.glgraphics.*;
   import javax.media.opengl.GL;
   
   GL gl;
   GLGraphics renderer;
   void setup()
   {
      height = 768;
      width = 1024;
      size(width, height, GLConstants.GLGRAPHICS);
      renderer = (GLGraphics)g;
      gl = renderer.gl;
      gl.glHint(gl.GL_LINE_SMOOTH_HINT, gl.GL_DONT_CARE);
   }
   
   void draw()
   {
     gl.glEnable (gl.GL_LINE_SMOOTH);
     renderer.noLights();
     renderer.beginGL();
     gl.glLineWidth(4.0);
     gl.glBegin(gl.GL_LINES);
     gl.glColor3f(0,0,0);
     gl.glVertex2f(0,0);
     gl.glColor3f(0,0,1);
     gl.glVertex2f(width,height);
     gl.glVertex2f(300,4);
     gl.glEnd();
     renderer.endGL();
     gl.glDisable (gl.GL_LINE_SMOOTH);
   }
