For CS4390 in Fall 1998, we were asked to design an elementary ray-tracing application. The program was to produce images that exhibited diffuse reflection (using Lambert's law and ambient light), specular reflection, and shadows. The program rendered spheres and polygons.

In CS4391 in Winter 1999, we expanded on this application by adding the ability to render cylinders, apply images to rendered objects, and to transform objects by combining them with other objects. Samples of the output appear below.

A Sphere	Two Spheres
A Sphere Minus A Sphere	The Intersection Of Two Spheres
A Flattened Sphere Minus A Cylinder	A Flattened Sphere Minus Two Cylinders
Cylinders And Spheres Make A Cage	Sphere With Texture Applied
Rotated Sphere And Texture	Cylinder With Texture Applied
A Sphere Flattened	A Sphere Stretched
Three Spheres Stretched And Joined	Two Spheres Stretched And Joined
