QRhi abstraction on top of Vk and D3D Raytracing

Hello!

We are trying to implement raytracing on top of QRhi in our app https://ossia.io as part of our GSoC internship: https://sat-mtl.gitlab.io/collaborations/google-summer-of-code/posts/2025-proposals/proposal-yunmaoleo-advanced-rendering-pipelines-in-ossia-score-with-raytracing/

One thing that we would like to consider is to write our code in such a way that could be eventually upstreamed to Qt itself.

Would there be any guidelines or existing R&D that has been done outside of the qvkrt prototype which would allow us to develop in the most efficient way possible?

Kind regards,
