glTF 2.0 Sample Assets

Introduction

This Repository is a curated collection of glTF models that illustrate one or more features or capabilities of glTF.

Lists

A website for browsing the sample assets can be found at https://github.khronos.org/glTF-Assets/. It allows searching for assets based on keywords and filtering the asset list based on tags. It offers an interactive preview of the sample assets, including basic inspection functionality and a summary of the description of the assets and their metadata.

Additionally, dedicated lists of assets are generated as markdown files, for browsing them directly here on GitHub. All lists include the model name, screen shot, link to display the model in Sample Viewer, a short description, and the license/credits for the model. The following lists are available:

• Showcase (#showcase) for models that are showcased in Khronos publicity. These are usually complex models with high visual quality.
• Complete for a complete list of all models.
• Testing (#testing) for models intended to be used for testing of viewers, converts, and other software systems.
• Core Only (#core) for models that only use glTF 2.0 core features and capabilities (no extensions).
• Video Tutorials (#video) for models used in any glTF Tutorial video.
• Written Tutorials (#written) for models used in a written glTF Tutorial.
• PBR tests (#pbrtest) for models that are illustrating the effect of PBR properties.
• Issues (#issues) for models with one or more issues that need to be resolved.

A summary of the model license is shown in each display, but see the README.md in each model's directory for detailed license information.

Model Contents

Sample glTF 2.0 models are provided in one or more of the following forms of glTF:

• glTF (.gltf) with separate resources: .bin (geometry, animation, skins) and .jpg or .png image files. The supporting files are easily examined when separated like this, but must be kept together with the parent glTF file for the model to work.
• glTF Embedded (.gltf) with embedded resources as Data URIs. This form is intended for very small binary payloads, similar to the use of small data URIs in HTML/CSS. This form should be avoided except as needed for a specific use case.
• Binary glTF (.glb) using the binary container format. These are easily shared due to the bundling of all the textures and mesh data into a single file.

Contributing Models

Sample models help the glTF ecosystem, if you are able to contribute a model, see the contributing section.

Model Publishing Services with glTF Download Capability

• Sketchfab offers auto-conversion of all of its downloadable models, including PBR models, to glTF format.
• Poly Haven offers CC0 (public domain equivalent) HDRIs, PBR textures, and glTF models.

Other glTF Models

For additional glTF models, see:

• Khronos glTF Asset Generator offers an extensive suite of test models to exercise each part of the glTF specification.
• Cesium's demo models and unit test models.
• Flightradar24's GitHub repo of aircrafts.
• Kenney • Assets hundreds of themed low-poly assets (nature, space, castle, furniture, etc.) provided by Kenney under CC0 licenses, including 30+ pirate themed models.

Obsolete Interface

To make this repository cleaner, the previous glTF-Sample-Models repository was archived in place. All glTF 1.0 and sourceModels files were removed from this repository. The major changes to the report are:

• The primary branch name was changed to main (from _master).

• 2.0 directory was renamed to Models

• All non-model folder READMEs were also removed

• Assets without licenses or licenses that were not suitable for use in this collection were removed

  • 2 Cylinder Engine
  • Buggy
  • Gearbox Assy
  • Reciprocating Saw

• The following models may be removed if a suitable use cannot be established

  • Antique Camera
  • Box Textured
  • Box Textured not 2^N
  • Cesium Man
  • Cesium Milk Truck

For the assets that remained, there were no changes to the Asset name. READMEs were provided to assist in navigation to any directories that were removed or substantially changed.
