GLTFQuickLook

GLTFQuickLook is a macOS Quick Look plugin that renders glTF assets directly in the Finder preview pane. It supports both the JSON‑based *.gltf* format and the binary *.glb* variant, allowing users to inspect 3‑D models without opening a separate application. The plugin integrates with the system’s Quick Look service, so selecting a glTF file and pressing the space bar displays a live preview of the model, including textures and basic lighting.

The tool is intended for developers, artists, and anyone who works with glTF files on macOS and wants a fast way to verify model contents. It runs on macOS 10.13 (High Sierra) or later and can be installed via Homebrew Cask or manually by copying the generator into the appropriate Quick Look directory and clearing the quarantine attribute. After installation, the Quick Look cache is refreshed to make the preview available.

Source code is available on GitHub, and the project can be built from source using Carthage and Xcode. Related utilities such as GLTFSceneKit provide additional glTF handling for SceneKit applications.
