This package contains the DirectXMath library, an all inline SIMD C++ linear algebra library for use in games and graphics apps.
This code is designed to build with Visual Studio 2019 (16.11), Visual Studio 2022, or clang/LLVM for Windows. It is recommended that you make use of the latest updates.
These components are designed to work without requiring any content from the legacy DirectX SDK. For details, see Where is the DirectX SDK?.
DirectXMath Files (in the DirectX C++ namespace)
- DirectXMath.h - Core library
- DirectXPackedVector.h - Load/Store functions and types for working with various compressed GPU formats

- Contains YAML files for the build pipelines along with some miscellaneous build files and scripts.
Officially the library is supported with Microsoft Visual C++ 2019 or later, clang/LLVM v12 or later, and GCC 9 or later. It should also compile with the Intel C++ and MinGW compilers.
When building with clang/LLVM or other GNU C compilers, the
_XM_NO_XMVECTOR_OVERLOADS_ control define is set because these compilers do not support creating operator overloads for the
XMVECTOR type. You can choose to enable this preprocessor define explicitly to do the same thing with Visual C++ for improved portability.
To build for non-Windows platforms, you need to provide a
sal.h header in your include path. You can obtain an open source version from GitHub.
With GCC, the SAL annotation preprocessor symbols can conflict with the GNU implementation of the Standard C++ Library. The workaround is to include the system headers before including DirectXMath:
#include <algorithm> #include <utility> #include <DirectXMath.h>

The xboxmath library was originated by Matt Bronder with contributions from Sakphong Chanbai and David Hefner for the Xbox 360.
The xnamath library for the DirectX SDK and Xbox XDK was the work of Chuck Walbourn and Becky Heineman based on xboxmath, with contributions from Jeremy Gup, Dan Haffner, Matt Lee, Casey Meekhof, Rich Sauer, Jason Strayer, and Xiaoyue Zheng.
The DirectXMath library for the Windows SDK and Xbox One XDK is the work of Chuck Walbourn based on xnamath, with contributions from Darren Anderson, Matt Lee, Aaron Rodriguez Hernandez, Yuichi Ito, Reza Nourai, Rich Sauer, and Jason Strayer.
Thanks to Dave Eberly for his contributions particularly in improving the transcendental functions.
Thanks to Bruce Dawson for his help with the rounding functions.
Thanks to Andrew Farrier for the fixes to
XMVerifyCPUSupport to properly support clang.
Thanks to Scott Matloff for his help in getting the library updated to use Intel SVML for VS 2019.
