Blender 4.4 will import/export OpenUSD with displacements (Feb'25).
Realtime rendering with Meshes/SubD and Displacements is currently not supported on Apple, but it's mentioned in the feature list since (over) a year now. And I already saw unintended(?) exports from ObjectCapture with "unused" .exr displacement maps early 2023.
It looks to me as WWDC25 will bring it to iOS 19 and visionOS 3.
I also hope for <model>.

Even with the main focus on extending glTF, these Behavior-Graphs could be discussed for #interactiveUSDZ as well

@twostraws @mikaelacaron For all who don't know what I'm talking about. Here'rs my open source pipeline to create #interactiveUSDZ files to load into ARQL and hopefully soon also into <model>.

Great to learn that Apple will introduce its own xr game engine next month.
My personal expectations:
- for both the new headset and iPhones with cheap VRgoggle-case
- Support for SubD-surfaces w/ displacement maps
- run many XR Apps/games simultaniously
- keep #interactiveUSDZ
- Support for MaterialX & procedural looks
- in/out events for <model> and WebXR with the native StereoAR mode (both need Safari to stay active parallel to AR/XR)
- RealTime NURB, PointCloud rendering/relighting

@BenHouston3D The main difference btw USD(Z) and glTF is how data and "opinions" are / can be managed. The USD file only works with the battle hardened USD software framework, written in 64bit C++. The possibilities of USD go far beyond what glTF was made for.
And since iOS13.1 the feature set of #interactiveUSDZ also includes declarative interactions, not only asset data (meshes, materials, textures) like glTF/glb.
The current discussion about glfx and your great work comes almost 3 years later
