## What it is
Draco is an open-source C++ library from Google for compressing and decompressing 3D geometric meshes and point clouds. It improves the storage and transmission of 3D graphics, with WASM/JavaScript decoders for web use and glTF integration.

## Use cases
- compress 3D mesh files for smaller downloads
- reduce point cloud storage size
- stream 3D models to web browsers efficiently
- compress glTF assets with Draco extension
- decode Draco-compressed 3D models in JavaScript or WASM

## When to choose
- you need to shrink 3D mesh or point cloud assets for storage or network transmission
- you serve 3D models on the web and want faster load times
- you work with glTF pipelines and need Draco compression support

## When to avoid
- you need lossless compression of arbitrary binary files
- you require editing or manipulating mesh geometry rather than compressing it
- your target viewers do not support the Draco decoding extension

## Facets
- artifact type: library
- maturity: stable
- function: compression, graphics, image-processing
- domain: graphics, web-development, computer-vision
- platform: cpp, cross-platform, wasm
- tags: 3d-meshes, point-clouds, gltf, codec, 3d-graphics, game-development, javascript
