JetBrains .NET Day Online '23
summary
Recreates Wolfenstein 3D in F# and shows the actual code and demo, not just slides: a working renderer that runs in the browser via Fable to JS and .NET desktop (Silk/OpenGL) and loads real Wolfenstein maps and textures. The talk steps through the raycaster math and raycasting with DDA, how sprite ordering/clipping and texture columns work, how assets are decompressed (RLE + “Carmack” compression), and why AI was left for later. Source on GitHub; project took about 4–6 months part‑time and the renderer demonstrably runs.
