Soft-Raster Scoreboard

College football replays drawn by a software rasterizer. Every pixel is computed in JavaScript into a Uint32Array, with no GPU, WebGL, or WebGPU, then pushed to a canvas with putImageData.

The pitch

A tiny CPU-only software rasterizer in JS or WASM that turns match stats (xG, shots, possession) from a Premier League or college football game into a stylized 3D replay, with no GPU or WebGL. Pick a game and watch the heatmap.

Why now

'I love software rendering' is resonating on HN, and football match searches are huge this weekend (Everton–Chelsea, BYU–Notre Dame, Man City, Liverpool). That makes it easy to demo with real data.

The factory pitched this as “Software-Rendered Scoreboard: Soft-Raster Football Match Replays.” Devin built and shipped it from that spec.
