# 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](https://github.com/google/draco).
|
||
|
|
* **glTF:** Builds targeted by the [glTF mesh compression extension](https://github.com/KhronosGroup/glTF/tree/master/extensions/2.0/Khronos/KHR_draco_mesh_compression), tracking the [corresponding Draco branch](https://github.com/google/draco/tree/gltf_2.0_draco_extension).
|
||
|
|
|
||
|
|
Either variation may be used with `DRACOLoader`:
|
||
|
|
|
||
|
|
```js
|
||
|
|
var dracoLoader = new DRACOLoader();
|
||
|
|
dracoLoader.setDecoderPath('path/to/decoders/');
|
||
|
|
dracoLoader.setDecoderConfig({type: 'js'}); // (Optional) Override detection of WASM support.
|
||
|
|
```
|
||
|
|
|
||
|
|
