Show HN: TTF-DOOM – A raycaster running inside TrueType font hinting

TrueType fonts have a hinting VM that grid-fits glyphs. It has a stack, storage area, conditionals, function calls, and it turns out it's Turing-complete. So I built a raycasting engine in the hinting bytecode. The glyph "A" in the font has 16 vertical bar contours. The hinting program reads player coordinates from font variation axes via GETVARIATION, does DDA ray marching against a tile map in the storage area, and repositions bar heights with SCFS. It ends up looking like a crude Wolfenstein-style view. Small visuzlization: https://github.com/4RH1T3CT0R7/ttf-doom/blob/main/docs/media... About 6.5 KB of bytecode total - 13 functions, 795 storage slots, sin/cos lookup tables. JS handles movement, enemies, and shooting, then passes the coordinates to the font through CSS font-variation-settings. The font is basically a weird GPU. The weirdest parts: - TrueType MUL does (a b)/64, not a b. So 1*4=0. The DIV instruction is equally cursed. - No WHILE loops. Everything compiles to recursive
