openusd

USD is an open-source framework developed by Pixar for the efficient interchange of 3D computer graphics data across different software applications.

This project aims to implement OpenUSD library in plain Rust (with no native C++ dependencies).

Documentation

The following list of docs was used during crate development:

• User documentation
• Book of USD
• API Documentation
• USD Cookbook

Supported features

The library can read all major USD formats. Here's what's currently supported:

• usdc (binary format) - for the list of supported features, refer to #1
• usda (text format) - can read most text files, corner cases possible
• usdz (zip archive format) - can read archived text/binary files
• Variable Expressions evaluator.
• DOM support is WIP: #15

If you encounter a file that can't be read, please open an issue and attach it for further investigation.
