Recreating Wolfenstein 3D in F#
summary
Recreates Wolfenstein 3D using F# + Fable and cross‑compiles to desktop .NET with Silk/OpenGL, implementing an actual rasterized ray caster (320-column DDA per frame), texture mapping by writing into a byte array, depth-sorted 2D sprites including orientable sprites (8 directions + animation frames), and decompresses original assets with RLE plus Carmack compression. Code is on GitHub, rendering and AI are implemented, the browser and desktop builds run though a desktop demo briefly crashes during the talk; development took about 4–6 months.
