# Create Draco Files
|
|
|
|
For creating Draco™ (`.drc`) files, there are multiple options.
|
|
|
|
## Command Line Tool
|
|
|
|
Draco's [Encoding Tool][dracoEncoder] is a command line tool that is able to convert a mesh or point cloud into a Draco (`.drc`) file. It supports the following input types:
|
|
|
|
- [Wavefront OBJ (`.obj`)][obj]
|
|
- [PLY][ply]
|
|
- [STL][stl]
|
|
|
|
Example for encoding a Wavefront OBJ (`input.obj`) into a Draco file (`output.drc`):
|
|
|
|
```shell
|
|
draco_encoder -i input.obj -o output.drc
|
|
```
|
|
|
|
See the [`draco_encoder`][dracoEncoder] documentation for usage details.
|
|
|
|
Unfortunately there's no binary distribution, so you have to build the executable yourself following Draco's [build instructions][dracoBuild].
|
|
|
|
> **Tip:** Similar to the Encoding Tool there's a [glTF Transcoding Tool][dracoGltfTranscoder] that it able to apply Draco compression on glTF files. See [Draco and glTF](do-more.md#draco-and-gltf) for more information.
|
|
|
|
## Within Unity
|
|
|
|
In the [*Scene/GameObject Encoding/Decoding via Menu* sample](sample-scene-encode-decode.md) you'll find an Editor script that lets you encode meshes to Draco within the Editor.
