IMAGE DESCRIPTION:
This view of Larry Niven's Ringworld displays the surface of the
Ringworld in daylight and in the artificial night created by the
Shadow Squares, not visible in this view.
DESCRIPTION OF HOW THIS IMAGE WAS CREATED:
This image is a study in procedural textures. fBm noise was used
to create the Ring surface textures and the star patterns. The
soft shadows were created by using area lights for the Sun. The
Sun is divided into six pieces to make this work correctly.
There is very little geometry in the scene.  Only the cylinder
of the Ring and the sphere for the stars are visible, although
there is other geometry not visible in this scene, such as the
shadow squares and the sun.
