Unreal Render Hardware Interface (RHI) is one of 6 APIs that [Unreal Engine](https://apis.io/providers/unreal-engine/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include D3D12, GPU, Graphics, Metal, and Rendering. The published artifact set on APIs.io includes API documentation.

The Render Hardware Interface is Unreal's abstraction over graphics APIs (Direct3D 11/12, Vulkan, Metal, OpenGL ES). Engine and plugin developers write rendering code against the RHI rather than directly against a GPU API, and the RHI maps that code onto the active backend at runtime.
