This project generates customizable 3D versions of emoji images. It takes the flat SVG artwork from Twemoji, an open emoji set, and turns each one into a 3D model you can preview and export. You can choose from several shape presets, such as coins or speech bubbles, adjust parameters, watch a live preview in your browser, and export the result as a GLB, OBJ, STL, or USDZ file, formats commonly used in games, augmented reality, and other 3D software. It is built with Three.js, a JavaScript library for 3D graphics in the browser. Under the hood, each emoji SVG is split into its individual colored shapes, and every shape is extruded, meaning stretched into a solid 3D form, then stacked with tiny offsets so the layers do not overlap oddly. The result is mounted onto a shape base like a coin or bubble, or exported flat on its own. An optional merge materials step combines all the colors into a single texture image, which keeps the final file simple enough to import cleanly into game engines. Beyond the interactive web app, the project includes a command line tool for generating many emojis in bulk. Using it requires two terminal windows: one running the development server, since the command line tool renders through a headless browser, and a second for issuing the generate commands. For people who do not want to generate their own, the maintainer also offers pre made packs of all 4,009 Twemoji emojis in bubble, coin, and flat shapes, downloadable from Google Drive. The code itself is released under the MIT license, while the generated graphics use a separate Creative Commons Attribution 4.0 license, so anyone reusing the exported emoji models should credit the source.
