Render Hardware Interface

This section contains technical details about the Render Hardware Interface (RHI) in Atom. The RHI is a low-level layer in the rendering pipeline that communicates with the backend graphics API. The RHI Gems are part of Atom and you need at least one compatible backend for your platform to render something on screen.

The RHI layer supports three backends:

  • DX12 backend: Supported on Microsoft Windows 10 and above.
  • Vulkan backend: Supported on Microsoft Windows 10 and above, Linux and Android.
  • Metal backend: Supported on Apple macOS (Intel x86_64) and iOS (iPad and iPhone).
