## Overview

This USD viewer renders Universal Scene Description models directly in your browser using WebGL. USD (.usd, .usda, .usdc, .usdz), developed by Pixar, is the modern open standard for 3D scene interchange in film, animation and AR. Pick a sample model or choose your own USD file to preview it in an interactive 3D viewport, with no upload.

## When to use

- You received a .usd or .usdz file from a 3D artist or AR app and want to view it.
- You need a quick, private preview of a Pixar USD scene before importing it.
- You want to inspect a USD model's geometry and structure on any device.

## How it works

- Select a built-in sample model or choose your own .usd / .usda / .usdc / .usdz file.
- The viewer loads the model with WebGL (three.js USDLoader) in your browser — nothing is uploaded.
- Rotate, zoom and pan to inspect the 3D model.

## Use cases

- Previewing Pixar USD assets for film and animation.
- Inspecting AR Quick Look .usdz models.
- Checking USD scenes from Apple and Pixar pipelines.

## Samples

- **Display Color USD Model**: A Universal Scene Description 3D model sample for in-browser preview

## Frequently asked questions

### What is a USD file?

USD (.usd, Universal Scene Description) is an open 3D scene format developed by Pixar Animation Studios. It is the industry standard for composing, animating and exchanging 3D scenes in film production and AR. Variants include .usda (ASCII text), .usdc (binary crate), and .usdz (single-file package for AR Quick Look).

### Are my USD 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 .usdz?

.usdz is the packaged version of USD — a single uncompressed ZIP file containing the USD scene and all its texture resources. It is the format Apple uses for AR Quick Look on iOS and the web.
