- **Category:** 3D Models

- **Supported formats:** .glb, .gltf

## Overview

This GLB viewer renders glTF 3D models directly in your browser using WebGL. GLB (.glb) is the binary container version of glTF, the modern open standard for 3D assets on the web. It bundles geometry, materials, textures and animations into a single file. Pick a sample model or choose your own .glb / .gltf file to preview it in an interactive 3D viewport, with no upload.

## When to use

- You received a .glb or .gltf file and want to view it without Blender or other 3D software.
- You need a quick, private preview of a 3D model before importing it.
- You want to inspect a glTF model's geometry and materials on any device.

## How it works

- Select a built-in sample model or choose your own .glb / .gltf file.
- The viewer loads the model with WebGL (three.js) in your browser — nothing is uploaded.
- Rotate, zoom and pan to inspect the 3D model from every angle.

## Use cases

- Previewing game and AR/VR assets.
- Inspecting 3D models for web and app development.
- Checking glTF exports before deployment.

## Samples

- **Sample GLB Model**: A GLB 3D model sample for in-browser preview

## Frequently asked questions

### What is a GLB file?

GLB (.glb) is the binary version of glTF (GL Transmission Format), the open standard for 3D on the web. Unlike .gltf which uses external files for textures, .glb bundles geometry, materials, textures and animations into a single binary file.

### Are my GLB files uploaded?

No. Models you open from your device stay on your device and are rendered locally with WebGL. Only the public sample model is requested from the server.

### What is the difference between .glb and .gltf?

.gltf stores the 3D data as JSON with separate binary (.bin) and texture files. .glb packs everything into one binary file for easier distribution. Both are the same glTF format — the viewer supports both.
