29. Multisampling

• Helps to smooth out polygons

• Creates another buffer (color, depth and stencil)

• All primitives are sampled multiple times, then "averaged"

• You take a performance hit here, but it looks good:

  
      glutInitDisplayMode(
          GLUT_DOUBLE | GLUT_RGB | GLUT_DEPTH | GLUT_MULTISAMPLE
          );
  
  

  Then:

  
      glEnable( GL_MULTISAMPLE );
  
  

• Note: Point/Line antialiasing is disabled when multisampling is enabled
