This repository contains my 1991 thesis (converted to HTML from the original nroff sources), as well as the original code for my 4D wireframe viewer and my 4D raytracer.

The thesis is now a single all-inclusive HTML file: Four-Space Visualization of 4D Objects.

See the thesis/ directory for my thesis source files and associated material.

wire4 is my 4D wireframe viewer. It was written to run on an SGI Iris workstation. It reads in arbitrary 4D wireframes from a simple text file and displays them interactively. The code has not been maintained, though, and will not run on most modern computers.

ray4 is the 4D raytracer. It is written in standard C, and reads from and writes to standard output, so should be able to run on most computers. The output is a 3D RGB image that can be displayed with a variety of methods.

You can send any questions to me at [email protected]. Also, now that GitHub has a discussions feature, feel free to start a conversation in the discussions section.

I'm contacted from time to time by others who have referenced my thesis or are embarking on 4D visualization work of their own. Here are links to other work I've seen.
