## What it is
glTFast is a Unity package for efficiently importing and exporting glTF 3D files at runtime or in the Unity Editor. It supports the glTF 2.0 specification and many extensions across all platforms and render pipelines, with a focus on speed, memory efficiency, and small build size.

## Use cases
- load glTF 3D models at runtime in a Unity game
- import glTF files into Unity as prefabs at design time
- export user-generated 3D content from a Unity app as glTF
- use Unity as a glTF authoring and export tool
- load 3D assets from a URL in WebGL builds
- handle Draco-compressed and KTX texture glTF assets

## When to choose
- you need fast, memory-efficient glTF loading in Unity at runtime
- you want glTF import/export across all Unity platforms and render pipelines
- you need support for glTF extensions like Draco or KTX

## When to avoid
- you are not working in Unity or a C#/.NET game engine context
- you need a general-purpose glTF viewer outside of Unity
- you require formats other than glTF for 3D asset exchange

## Facets
- artifact type: library
- maturity: active
- function: graphics, image-processing, sdk, plugin-system
- domain: graphics, web-development, cross-platform
- platform: cross-platform, windows, wasm
- tags: gltf, unity, 3d-models, draco, ktx, upm, runtime-loading, asset-import, asset-export, game-development, macos, linux, android, ios, web-server
