RayTracer

You can still make stuff that runs from the boot sector. You just won't have access to fancy graphics drivers. I found this: https://github.com/nanochess/RayTracer

when i wrote my very first ray tracer it didn't take me an entire weekend; it's about four pages of c that i wrote in one night http://canonical.org/~kragen/sw/aspmisc/my-very-first-raytra... since then i've written raytracers in clojure and lua and a raymarcher in js; they can be very small and simple last night i was looking at Spongy by mentor/TBC https://www.pouet.net/prod.php?which=53871 which is a fractal animation raytracer with fog in 65 machine instructions. the ms-dos executable is 128 bytes i think it's easy to get overwhelmed by how stunning raytraced images look and decide that the algorithms and data structures to generate them must be very difficult, but actually they're very simple, at least if you already know about three-dimensional vectors. i feel like sdf raymarching is even simpler than the traditional whitted-style
