Over the past few years, I've been working on a number of projects in part motivated by the need to replace legacy D3DX functionality. As noted on MSDN, all versions of D3DX are deprecated and are not shipped with the Windows 8.x SDK. This includes D3DX9, D3DX10, and D3DX11. There are plenty of options for moving existing code over to newer, more supportable solutions most of which are now shared-source.

I've built a number of porting notes tables for each of these topics, and then realized today I don't have a single place to see it all. So here it is, the "D3DX porting mega-table" for Direct3D 11.

Direct3D 9: There are not many good replacements for the functionality in D3DX9 if you are still using Direct3D 9. You can make use of D3DCompile APIs directly with the legacy DirectX SDK, but newer versions of the D3DCompile DLL in the Windows 8.x SDK are not compatible with Windows XP for runtime use. You can use DirectXMath/XNAMath for Direct3D 9 instead of D3DXMath. The DDSWithoutD3DX sample supports Direct3D 9, and you can use DirectXTex and DirectXMesh when preparing content for use by Direct3D 9.

Direct3D 10: The best option for Direct3D 10.x applications is to update them to use Direct3D 11, and then utilize all the options here to replace legacy D3XD10. Porting the API is very straightforward, and Direct3D 11 is available on all supported platforms that have Direct3D 10.

Direct3D 12: There is a header that ships in the DirectX 12 samples on GitHub called d3dx12.h. It is all inline utility header which has no DLL or redistributable dependency, and can be used under the MIT license. It is not included in the Windows SDK. If you are looking for additional functionality, see the DirectX Tool Kit for DirectX 12, DirectXTex and DirectXMesh.

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.

ID3DX10Sprite	SpriteBatch
ID3DX10Font	SpriteFont, SpriteBatch
ID3DX10Mesh	Model, ModelMesh, ModelMeshPart
D3DXCreateBox D3DXCreateCylinder D3DXCreateSphere D3DXCreateTeapot D3DXCreateTorus	GeometricPrimitive
D3DX11CreateShaderResourceViewFromFile	CreateXXXTextureFromFile
D3DX11CreateShaderResourceViewFromResource D3DX11CreateShaderResourceViewFromMemory	CreateXXXTextureFromMemory
D3DX11CreateTextureFromFile	CreateXXXTextureFromFile
D3DX11CreateTextureFromResource D3DX11CreateTextureFromMemory	CreateXXXTextureFromMemory
D3DX11SaveTextureToFile	SaveXXXTextureToFile

 

The DXERR library is another helper that shipped in the legacy DirectX SDK. In Windows 8.x or later, you can just use FormatMessage to use the built-in error descriptions which support DirectX. Otherwise, the best replacement is to compile your own version of DXERR.

DXGetErrorString DXGetErrorDescription DXTrace

HLSL Functions

The HLSL compiler, shader reflection API, and related functionality has been broken out into it's own D3DCompile DLL 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.

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.

Background

A few folks have asked why the D3DX libraries were deprecated in the first place in the transition to the Windows 8.x SDK. D3DX has been a useful set of utility code for Direct3D applications since Direct3D 7, but has a presented a number of challenges over the years. The primary one is that as a 'closed-source' utility library; it was difficult to debug, resolve performance issues, or apply hot-fixes without taking a dependency on a newer release of the DirectX SDK. Second, with the security requirements that came with the adoption of the Secure Development Lifecycle (SDL) at Microsoft, the transition to a DLL rather than a static library created a redistribution requirement that complicated setup for many developers--note that static libraries have their own problems such as being specific to a particular release of the compiler including service pack level. D3DX9 itself became a bit bloated which resulted in a DLL larger than many EXEs that used it. Finally, the actual usable content of subsequent generations of D3DX left D3DX11 with not much in it. The need for useful utility code is still there, but it is now being solved with various 'shared-source' solutions rather than a monolithic closed-source DLL like D3DX.
