This is a not-particularly-sophisticated CPU renderer that I wrote to cement my understanding of the OpenGL pipeline's general structure, which it's ((very) loosely) based on. It can draw a ~400-triangle sphere-with-holes with texturing and basic Phong shading in 720x720 at about 30 FPS on my (fairly powerful) laptop.

Working with some kind of GUI API to display the output would be out of scope (the only dependencies are libc and libm), so the program streams video to stdout as an undelimited sequence of raw RGBA images. If you have mpv installed, you can use the play.sh wrapper script to watch the output in real time.

The LICENSE file does not apply to gear.pam, dna_vertices, or dna_triangles, which are not my original work.
