Next meeting, @Francois_Mazen, @Lucas_Givord and myself would like to have a deep dive look into @pieper’s [Slicer Live](https://github.com/pieper/SlicerLive) WebGPU implementation.
Our goal is to see what would be required on VTK’s side / WebGPU backend to have the same type of rendering moving forward.

## macOS arm64 builds
- `recoil.kitware.com` has been setup for arm64 builds
- [SlicerPreview - Build Summary](https://slicer.cdash.org/builds/4363126)
- Qt 6.11.1 build
- only blocking issue is the package manager has hardcoded `arch` options, so the client and server needed to be updated before packages can be hosted on the server.
