Draco 3D Data Compression

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.



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:

Either variation may be used with THREE.DRACOLoader:

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