pxr_rs

Rust interface for OpenUSD.

Status

This project is in early development and is not ready for production use. Not all of the OpenUSD API is currently exposed.

Documentation and examples are currently lacking but will be the focus once the crates are more stable.

Currently, OpenUSD 22.11 compiled via build options specified via the default features of pxr_sys is the primary target upon which the project is being developed.

Overview

The workspace contains these packages:

• pxr_build: Helper crate for building OpenUSD bindings
• pxr_sys: Unsafe Rust bindings for OpenUSD
• pxr: Safe Rust bindings for OpenUSD (WIP)

Most of the bindings are automatically generated from the OpenUSD headers using autocxx, while some are hand-written via rust-cpp and additional macros inside pxr_build. The C++ library of OpenUSD can be automatically downloaded and compiled during the cargo build process if the vendored feature is enabled.

Dependencies

The complete list of dependencies can be found within Dockerfile.

Enabling of additional non-default features might require additional dependencies. This is currently not tested/documented.

Instructions

Rust

Add pxr as a Rust dependency to your Cargo.toml manifest.

[dependencies]
pxr = { version = "0.2" }

Note that the first build might take up to 50 minutes because OpenUSD will be automatically downloaded and compiled with the vendored feature enabled. The artifacts will be cached in OUT_DIR and reused for subsequent builds.

Alternatively, you can specify the path to an existing OpenUSD installation directory via the following environment variable.

export OPENUSD_PATH=/path/to/pxr/openusd

It is highly recommended to use lld or mold linker because ld might currently fail.

.docker/build.bash ${TAG:-latest} ${BUILD_ARGS}

.docker/run.bash ${TAG:-latest} ${CMD}

.docker/dev.bash ${TAG:-latest} ${CMD}

.devcontainer/open.bash

.docker/join.bash ${CMD:-bash}
