Reconstruct any image using primitive shapes, runs in-browser via WASM

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.

From the sources

Primitive-Playground is a web app that transforms images into abstract art. It helps bring depth to the beautiful images you capture. You can experiment with various conversion patterns to suit your preferences.

A web app that reconstructs any image using primitive shapes; port of fogleman/primitive - taiseiue/primitive-playground

This is a web application that converts any image into one expressed solely through geometric shapes. It runs on WebAssembly, with all processing performed entirely on the device. The algorithm attempts to reproduce the input image using only predefined shapes, minimizing the error between the input image and the image being drawn. This process is iterative, adding one shape at a time. The progress of shapes being added can be observed. This is a WASM port and Web UI for the idea by fogleman: fogleman/primitive . The original primitive is a Go-based CLI tool and not easy to use, so I made it available from a browser. Please consider starring fogleman/primitive . You can use it by accessing…from github.com

In the maker’s words, at launch

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…

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
