Some parts of the flow are programmable.

In the Direct3D rendering pipeline, data flows from several sources, like the tributaries of a river. You can also use Direct3D 10.1 and Direct3D 11 APIs with Windows Vista with Service Pack 2 (SP2).

Use Direct3D 10.1 and Direct3D 11 APIs with Windows 7 and later.Only Direct3D 10-level and later hardware support Direct3D 10 APIs. Use Direct3D 10 APIs with Windows Vista and later.All hardware supports Direct3D 9 APIs, even newer Direct3D 11-level hardware. Use Direct3D 9 APIs with Windows XP and later.If you want to target Windows 8 and later, use Direct3D 11 APIs.The Direct3D API version that you choose depends on the operating system and hardware level that you want to target. Desktop apps can use the full set of the XInput APIs, while Windows Store apps and UWP apps can use most of the XInput APIs for more info, see XInput Versions. But Windows Store apps, UWP apps, and desktop apps can use the full set of the XAudio2 and DirectXMath APIs. Starting with Windows 8, we no longer actively support the XNA framework for desktop apps.If you write a desktop app, you can use the full set of Direct3D 11, DXGI, and HLSL APIs.To learn how to write a Direct3D 11 Windows Store app, see Create 3D graphics with DirectX. For a list of these APIs, see Win32 and COM APIs for UWP apps.

If you want to write a UWP app, use a subset of Direct3D 11, DXGI, and HLSL APIs.

The Direct3D APIs that you choose depend on the style of app you want to write. You don't wait for immediate feedback from the operation. You set up a bunch of rendering or compute state and then start an operation. Newer GPUs have hundreds or thousands of parallel processors.

Is designed to drive a separate graphics-specific processor.

But you still need to know how to draw 3D graphics.

Hides different GPU implementations behind a coherent abstraction.

What is Direct3D?ĭirect3D is a low-level API that you can use to draw triangles, lines, or points per frame, or to start highly parallel operations on the GPU. Direct3D is a low-level API for drawing primitives with the rendering pipeline, or for performing parallel operations with the compute shader.
