Stills from an Animation of the Computer
Surfaces lit using conventional polygon shading.
Figure 1.1 Software by Ace Computing was used to produce these still illustra-
tions from a conventional video animation of the Acorn Archimedes computer.
Polygon shading colours the entire surface of each facet a constant shade, which
is determined by its colour and the light and shadow falling on it. The scenes
produced are therefore crisp, but somewhat unrealistic. Note: this very early race
tracing software produced images at even a low resolution very slowly and so
parts of these 18 frames can appear jagged.
