# Draco 3D Data CompressionDraco 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.[Website](https://google.github.io/draco/) | [GitHub](https://github.com/google/draco)## ContentsThis 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 `THREE.DRACOLoader`:```jsvardracoLoader=newTHREE.DRACOLoader();
