The images were generated with a standard Amiga with 512k memory. A ray tracing method was used, which simulates rays of the light reflecting within a mathematically defined scene. Each image requires the calculation of 64,000 light rays and takes approximately 1 hour to generate. An image is compressed to about 10k bytes for storage. Images are expanded in less than 30 millisencods. THe Amiga hold and modify mode is employed so that up to 4096 colors can be displayed at one time.
