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