Note
When mode and flag are set with the values shown here, they default to creating a one-sided primitive that will be rendered with no semitransparency. To alter these, see earlier notes. Pigment refers to the inherent colour of the primitive, before lightsources alter the appearance on screen. A gradient pigment has a different RGB value at each vertex, and by using the same interpolation algorithm that gouraud shading uses, a smooth transition between colours is achieved.
