## What it is
The official Khronos glTF 2.0 Sample Viewer, a web application that renders glTF 2.0 3D models with physically-based rendering using WebGL 2.0. It supports a wide range of glTF extensions including material, animation, and compression extensions.

## Use cases
- view gltf 3d models in browser
- test pbr materials for gltf files
- preview 3d assets before exporting
- check gltf extension compatibility
- inspect 3d model rendering in webgl
- validate gltf 2.0 files visually

## When to choose
- you need a reference implementation for correct glTF 2.0 PBR rendering
- you want to visually verify glTF assets and their extensions in a browser
- you are developing glTF exporters and need a ground-truth viewer

## When to avoid
- you need a full 3D engine or scene editor rather than a model viewer
- you require game-engine integration like Unity or Unreal import
- you need offline desktop viewing without a browser
