Show HN: Reconstruct any image using primitive shapes, runs in-browser via WASM
I built a browser-based port of fogleman/primitive — a Go CLI tool that approximates images using primitive shapes (triangles, ellipses, beziers, etc.) via a hill-climbing algorithm.
The original tool requires building from source and running from the terminal, which isn't exactly accessible. I compiled the core logic to WebAssembly so anyone can drop an image and watch it get reconstructed shape by shape, entirely client-side with no server involved.
Demo: https://primitive-playground.taiseiue.jp/ Source: https://github.com/taiseiue/primitive-playground
Curious if anyone has ideas for shapes or features worth adding.
