Does Coin3D have any plans to support Vulkan?

If not in the short term, could a simple tutorial be provided to explain how to replace the OpenGL backend with Vulkan？

I think this operation can enable community developers to experiment with such a replacement—thereby enriching Coin3D's ecosystem and improving performance?

As part of the work I am doing in FreeCAD, I am introducing a modern renderer abstraction in Coin which will allow eventually to write new renderers much more easily. I don't plan myself to work on a Vulkan renderer for now, but the infrastructure being worked on will make that much easier in the future.

Tritao, I'm interested in the abstraction layer you are working on. I would like to see Coin3D on Vulcan as well as Apple Metal. Have you created a project or github branch to track your experience?

My active WIP branch is at https://github.com/tritao/coin/commits/modern-gl/ but this is still very much in flux.

Previously I tried adding BGFX support as well https://github.com/tritao/coin/commits/bgfx, but have abandoned that idea for the moment and am solely focused on adding a modern GL-based renderer.

We could still target Vulkan with ANGLE, or re-use most of the same abstractions to add non-GL based renderers.

I don't know how helpful this is since I've diverged quite a lot from upstream Coin at this point, but I've been working on extracting a subset of Coin into a OS/rendering agnostic library (https://github.com/starseeker/obol) and I did manage to get a simple Vulkan demo working. The non-OpenGL backend support doesn't handle the full feature set (since OpenGL isn't available and some of Coin's features are tightly tied to it - I've not tried reworking the internals to that degree) but it can handle basic stuff so it might at least be good for some ideas.
