How to use the backend of dynamic rendering? Ex: vulkan / metal / DirectX 12

[zoujiaqing]

Skia support many rendering backends, such as how do vulkan、metal、D3D, call them in Avalonia?

macOS / iOS : metal
FreeBSD / Linux / Android : vulkan
Windows : DirectX

Currently only OpenGL has a builtin support via OpenGlControlBase. You can also use raw Skia directly via custom drawing operations (ICustomDrawOperation) and this would allow you to interface with your backend of choice. Avalonia still does not give a builtin way of using Direct3D or Vulkan backends but you can provide it yourself via ISkiaGpu.

Actual interop also varies based on how do you implement your rendering, if you render to a texture and let Skia use it then it will be simpler than trying to setup a framebuffer from a control.

See #9925
It's now possible to integrate directx and vulkan as well. Samples here https://github.com/AvaloniaUI/Avalonia/tree/master/samples/GpuInterop
Available in nightly, also will be part of 11.0-preview5 soon.
