Wireframe Model of the Three Vases

Introduction

I have long been interested in computer graphics. In the 1980s, I started writing a 3D modeler and renderer as a way to create images of things that do not exist.

Recently, I added radiosity to the renderer's capabilities. Radiosity simulates the diffusion of light among the objects in a scene in much the same way that it happens in the real world. The following wallpapers illustrate how closely a computer simulation can mimic reality.


Night Life

Mirrored spheres on a checkerboard are a sure sign of being computer-generated.


Mega Maze

This maze is made up of 300,000 triangles. The corners are darker than the open spaces.

Three Vases

The vases look much better after texture mapping, lighting, shading, ray tracing, and radiosity. If you look closely, you can see the virtual "room".
