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:

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