xatlas-wasm

WebAssembly build of xatlas — a small C++17 library that generates unique texture coordinates suitable for lightmap baking or texture painting. This package wraps xatlas in an ES module you can use from Node.js or the browser.

Quick Start

import createXAtlas from 'xatlas-wasm';

const xatlas = await createXAtlas();
const atlas = xatlas.createAtlas();

atlas.addMesh({ positions, indices });
atlas.generate();

const mesh = atlas.getMesh(0);
// mesh.vertices[i].uv  — atlas UV coordinates
// mesh.vertices[i].xref — index of the original input vertex

atlas.destroy();
