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.

In plain words
This tool reconstructs images using primitive geometric shapes like triangles, ellipses, and bezier curves through a hill-climbing algorithm. It brings the functionality of a command-line Go tool into the browser via WebAssembly, allowing users to upload images and watch them get approximated shape by shape entirely client-side. It is for anyone interested in generative art, image processing, or algorithmic design without requiring terminal access or software installation.
