Draco 3D Data Compression

Draco is an open-source library for compressing and decompressing 3D geometric meshes and point clouds. It is intended to improve the storage and transmission of 3D graphics.

Contents

This folder contains three utilities:

• draco_decoder.js — Emscripten-compiled decoder, compatible with any modern browser.
• draco_decoder.wasm — WebAssembly decoder, compatible with newer browsers and devices.
• draco_wasm_wrapper.js — JavaScript wrapper for the WASM decoder.

Each file is provided in two variations:

• Default: Latest stable builds, tracking the project’s master branch.
• glTF: Builds targeted by the glTF mesh compression extension, tracking the corresponding Draco branch.

Either variation may be used with THREE.DRACOLoader:

var dracoLoader = new THREE.DRACOLoader();
dracoLoader.setDecoderPath('path/to/decoders/');
dracoLoader.setDecoderConfig({type: 'js'}); // (Optional) Override detection of WASM support.
