I created a Vulkan implementation of NoesisGUI in a game engine me and my friends are developing which uses Vulkan as the underlying graphics API. I thought I could share it here if anyone wants to take a look. I haven't had time to test it very much. Tiled rendering hasn't been tested at all. All the GUI code can be found in "GUI/Core".

The GUIRenderer in the engine is part of our RenderGraph rendering system, basically it receives resource updates from the RenderGraph, currently just the back buffer and a depth/stencil texture, all the other resources are created by the GUI system itself.

Since NoesisGUI uses alot of dynamic state I had to create different caches, the most complicated one is GUIPipelineStateCache, it manages and creates new Pipelines when requested depending on different requested dynamic state features.
Examples of these are:

• Vertex Type
• Stencil Mode
• Blend Mode

Other examples of caches and managers are the buffer caches, descriptor set caches and the GUIShaderManager.

Great job! We are working in an official Vulkan renderer. Once we released it, please have a look at it to improve the offscreen part of your renderer.

EDIT: I added a link to this project here

Yeah, thanks, I'll be sure to do that!
