These are some povray images I created for for my Computing with Geometry class. fbi-color.jpg: A simple block that was cut to create shadows of the letters 'F' 'B' and 'I' on the walls. fbi-glass.jpg: Similar to the above, but using glass for the walls to provide reflections and transparency. quadric.jpg: Using quadric surfaces to create a scene of a table top with a bowl of water, a lava lamp, a candle, and a hanging lamp. quadric2.jpg: Similar project to create a toy horse.
