v23.11.7

What's New

• Extend Pixar.Usd.Stage with the ability to undergo scene traversal with the Pixar.Usd.Stage.traverse() function and the ability to open existing scenes with Pixar.Usd.Stage.open(_:load:) function.
• Resolve duplicate symbols with some wrapXXX() python functions due to Swift ignoring the hidden visibility attribute on those symbols.
• Initial working ability to create a new Usd.Stage with Pixar.Usd.Stage.createNew("HelloUSD.usda").
• Addition of the Pixar.Bundle API to automatically install all plugin resources across USD, use it like the following:

  Pixar.Bundle.shared.setup(.resources)
  
  // check your console for any coding errors here, if any are found please create a new issue from the link below.
  
  Pixar.Usd.Stage.createNew("HelloUSD.usda")

• Correct the paths used to register with PlugRegistry when using Pixar.Bundle.shared.setup(.resources), please create a new issue if you experience any crashes when creating a new USD stage with Pixar.Usd.Stage.createNew("HelloUSD.usda"), to ensure the configured paths match all systems and edge cases.
• Addition of the GfVec3f type from Pixar.Gf to the Swift API.
• Easily embed Vulkan for applications or libraries that link with SwiftUSD.
• Support successfully building SwiftUSD (in addition to MetaverseKit) with Xcode.

We are now prepared to commence comprehensive development of the Swift API for Pixar USD. Following the successful integration of each module so far, packed with umbrella headers that encompass the entirety of their associated header files.

Our current focus will be on ensuring Linux compatibility and transforming MetaverseKit into a cross-platform Swift package. Additionally, we will collaborate with the SwiftPM team to enhance the capabilities of the package manager. Our goal is to seamlessly incorporate this Package.swift file into the root of the official OpenUSD project, preserving its existing project structure.

• Powered by 👾MetaverseKit v1.3.7 🌍.

What's Fixed

• Provide a workaround related to Xcode's inability to build swift packages that depend on (more than one) .xcframework that contain a module.modulemap file to it's headers.

• Provide another Xcode workaround for Xcode's inability to build a target that does not provide object files, because its tooling is hardcoded to expect the output of at least some symbols for all libraries.

• Resolved a tiny but catastrophic error that was causing the Swift compiler to crash with no error given, the stack trace appeared it was getting hung up somewhere around here, at the following function in Tf.refPtr.h:

// swift hated this. 
friend T *get_pointer(TfRefPtr const &p) {
  return static_cast<T *>(const_cast<TfRefBase *>(p._refBase));
}

// this got things working seamlessly again.
using DataType = T;

friend DataType *get_pointer(TfRefPtr const &p) {
  return static_cast<DataType *>(const_cast<TfRefBase *>(p._refBase));
}

Usage

To use this release of Pixar's USD in your swift project, add the following to your Package.swift file:

dependencies: [
  .package(url: "/~https://github.com/wabiverse/SwiftUSD.git", from: "23.11.7"),
]

Note

Zero prerequisites, just run swift build in your own swift app, game, library, or plugin.
