DirectX Tool Kit for DirectX 11

Copyright (c) Microsoft Corporation.

October 17, 2022

This package contains the "DirectX Tool Kit", a collection of helper classes for writing Direct3D 11 C++ code for Universal Windows Platform (UWP) apps for Windows 11, Windows 10, Xbox One, and Win32 desktop applications for Windows 7 Service Pack 1 or later.

This code is designed to build with Visual Studio 2019 (16.11), Visual Studio 2022, or clang for Windows v11 or later. Use of the Windows 10 May 2020 Update SDK (19041) or later is required.

These components are designed to work without requiring any content from the legacy DirectX SDK. For details, see Where is the DirectX SDK?.

Release Notes

  • As of the September 2022 release, the library makes use of C++11 inline namespaces for differing types that have the same names in the DirectX 11 and DirectX 12 version of the DirectX Tool Kit. This provides a link-unique name such as DirectX::DX11::SpriteBatch that will appear in linker output messages. In most use cases, however, there is no need to add explicit DX11 namespace resolution in client code.

  • Starting with the July 2022 release, the bool forceSRGB parameter for DDSTextureLoader Ex functions is now a DDS_LOADER_FLAGS typed enum bitmask flag parameter. This may have a breaking change impact to client code. Replace true with DDS_LOADER_FORCE_SRGB and false with DDS_LOADER_DEFAULT.

  • As of the March 2022 release, legacy Xbox One XDK support requires the XDK April 2018 release or later.

  • As of the October 2021 release, the DGSLEffect no longer directly supports skinning. Instead, make use of SkinnedDGSLEffect which is derived from DGSLEffect.

  • As of the August 2021 release, MakeSpriteFont requires the .NET version 4.7.2 targeting pack to be installed to build.

  • Starting with the June 2020 release, this library makes use of typed enum bitmask flags per the recommendation of the C++ Standard section Bitmask types. This may have breaking change impacts to client code:

    • You cannot pass the 0 literal as your flags value. Instead you must make use of the appropriate default enum value: AudioEngine_Default, SoundEffectInstance_Default, ModelLoader_Clockwise, or WIC_LOADER_DEFAULT.

    • Use the enum type instead of DWORD if building up flags values locally with bitmask operations. For example, WIC_LOADER_FLAGS flags = WIC_LOADER_DEFAULT; if (...) flags |= WIC_LOADER_FORCE_SRGB;

  • The UWP projects and the Win10 classic desktop project include configurations for the ARM64 platform. Building these requires installing the ARM64 toolset.

  • When using clang/LLVM for the ARM64 platform, the Windows 11 SDK (22000) is required.

  • The CompileShaders.cmd script must have Windows-style (CRLF) line-endings. If it is changed to Linux-style (LF) line-endings, it can fail to build all the required shaders.
