Not trolling. I haven’t played with wasm at all. Perhaps if it can fill a 2k x 2k pixel image super fast it would be indistinguishable from my solution. If someone had coded this and open sourced it I’d love to use it
probably fill rates of 240 megapixels per second are going to be hard to reach consistently in javascript but 60 (1k × 1k) seems likely achievable without much in the way of tricks
