This page demonstrates the basics of scripting shapes RenderMan scene description (RIB) protocol. Writing RIB files by hand focuses attention on the use of color, opacity and the fundamental concepts related to xyz coordinate system. The preliminary renders have been done using basic shading so that the geometry can be more easily seen.
