As new versions of D3DX are shipped in future releases of the DirectX SDK, applications linking to earlier D3DX libraries will remain unaffected. This DLL corresponds to the D3DX headers the application is compiled against (named with the D3DX_SDK_VERSION constant in D3dx9core.h). By statically linking an application to D3dx9.lib, the application dynamically links to the corresponding retail D3DX DLL at run-time. Multiple releases of D3DX can reside independently on a single system simultaneously. Each folder only contains the headers, libraries, utility binaries, and license documents from the DirectX SDK release. They can also be handy for building other older programs. Applications linking against the version of D3DX in this release must also redistribute the runtime from this SDK. A collection of headers and libraries from some older releases of the DirectX SDK, mainly used to compile sfall. The D3DX library included in this release is dependent on the Direct3D runtimes that shipped with this SDK. The retail D3DX DLL is included in the redistributable provided in the SDK, and is automatically installed as part of Installing DirectX with DirectSetup.

Only one version of D3DX is provided in this release of the DirectX SDK. D3DX is provided as a dynamic-link library (DLL). If upgrading to a newer version of Direct3D and associated utility code is not an option, you can make use of the 3DX NuGet package rather than relying on the legacy DirectX SDK or DirectSetup.ĭ3DX is a library of tools designed to provide additional graphics functionality on top of Direct3D.
