In about 1990, I wrote a little raytracer in C++ as the course project for a computer graphics class at U. Oregon. About 5000 lines; seemed like a great way to learn the language.
Turns out I hate C++.
The scene is hard-coded to this:
Anyway, Julian Kongslie got my raytracer up to date and running again in 2007, fixing a long-outstanding memory allocation bug that caused slight indeterminism in the results.
This code has some OK reusable classes, and is not implausibly slow on a modern box. (In 2022, 1000x1000 takes me about 3.5s with 3×3 antialiasing. In 1990, 100x100 without antialiasing was minutes.)
Build with make, run with e.g. ./render 1440 1440. Turns
out non-square renders come out distorted. Should probably
fix that someday.
