Unreal Engine

Unreal Render Hardware Interface (RHI)

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.

Unreal Render Hardware Interface (RHI) is one of 6 APIs that Unreal Engine publishes on the APIs.io network.

Tagged areas include D3D12, GPU, Graphics, Metal, and Rendering. The published artifact set on APIs.io includes API documentation.
