DirectX
Definition
Microsoft APIs for graphics, media, audio, and related Windows workloads.
Detailed explanation
DirectX is Microsoft’s family of multimedia and graphics APIs for Windows and Xbox. Direct3D defines graphics interfaces, while related components cover input, audio, media, and shader tooling. A vendor driver translates API operations into commands for a particular GPU architecture. Direct3D feature levels describe capabilities exposed by hardware and its driver, whereas the DirectX version bundled with Windows describes available runtime interfaces. DXGI handles adapters, displays, and presentation, and shader models define programmable-language capabilities across related releases.
