Living without D3DX

General Helpers

The DirectX Tool Kit provides a number of helpers that are designed to simplify Direct3D 11 programming in the tradition of the original D3DX library. You can find the library on CodePlex and GitHub.

HLSL Functions

The HLSL compiler, shader reflection API, and related functionality has been broken out into it's own D3DCompileDLL for some time. D3DCompile is in the Windows 8.x SDK and is included with VS 2012 and VS 2013 Preview.

Texture Functions

The DirectXTex library is primarily intended for texture processing offline with tools, although it can also be used at runtime for doing texture block compression, mipmap generation, or handling more general image processing needs. DirectXTK is intended for use at runtime with light-weight helpers and image loaders, but does not provide support for general runtime texture format conversion. You can find both libraries on CodePlex and GitHub.

Performance/Profiling

D3DX9 included the entry-points intercepted by PIX for Windows for performance profiling. This is now handled by the DirectX runtime directly and is monitored by the Visual Studio Graphics Diagnostics tool.

D3DPERF_BeginEvent
D3DPERF_EndEvent
D3DPERF_SetMarker
D3DPERF_SetRegion
D3DPERF_QueryRepeatFrame
D3DPERF_SetOptions
D3DPERF_GetStatus

ID3DUserDefinedAnnotation which is supported by the DirectX 11.1 runtime on Windows 8.x and Windows 7 Service Pack 1 + KB2670838

If using DirectX 11.2+, you can use ID3D11DeviceContext2 directly for BeginEventInt, SetMarkerInt, and EndEvent.

UVAtlas Functions

The UVAtlas library is intended for isochart creation offline with tools, although it can be used at runtime. You can find the library on CodePlex and GitHub.

Note

Careful readers will note that there are a few omissions from this table.

• The ID3DXMatrixStack from D3DXMath doesn't have a new version, but it's actually pretty easy to implement your own. If someone has a burning need for this, please comment below.
• The Precomputed Radiance Transfer (PRT) simulator is only available in closed-source form in legacy D3DX9. There are a number of papers that cover this technology in the literature, and the most generally useful parts of this functionality are the SHmath functions which are available.
