  • Demo of assets viewing and interaction in Autodesk Forge in Chrome
    • Rendering, selection, and scene-inspection
    • A lot of work has been done on bindings
    • Custom changes to WebASM build of TBB

  • Conversion from USDZ into blender and out to GLTF is a great short term solution, but...
  • Worth doing test for conversion of animated models over time.
  • Makes a compelling case for a native Sdf plug-in for GLTF import/export.
  • Past initial mesh import, would USDSkel and GLTF bi-directional conversion be lossless?
  • Draco plugin may need to support native Draco files better, or does it matter in a separate Sdf plugin?
  • KTX as native Hio plugin would likely be mandatory, does Hio support unpacking direct to GPU texture via Hgi? (Brian from AMD hints at a yes)
  • Is MaterialX and its advances (especially in tackling WebASM) going to be the way forward for all shading interchange in USD.
  • OCIO and color accuracy again came up as important, but too large a topic compared to getting a better bare-bones implementation anyone can use.
  • Video Conference Link

  • Autodesk showed USD import into Forge.  Translates to Forge-native geometry.
  • Autodesk also working on a WebGPU Hydra delegate that does PBR shading.
  • A lot of overlap between the delegate above and Filament (i.e. SPIR-V tools running in browser)
  • TBB remains an issue that everyone is keen to solve.
  • Philippe Sawicki working on an MVP list for JS-bindings.
  • Dhruv Govil is interested in what can be leveraged from ASWF initiative to auto-gen Rust bindings.

JavaScript bindings, need a real strategy on how to tackle them.

See what changes have landed in /dev that may help reduce reliance on WebAsm-TBB and its CORS issues.

Working example of WebASM build of USD with a Hydra delegate for Filament

Ideally GitHub Pages version at https://marsupial.github.io/USD/extras/imaging/examples/hdFilament would be a live demo, but
