|
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 2017, Visual Studio 2019, or clang for Windows. It is recommended that you make use of the latest updates (VS 2017 15.9 update, or VS 2019 Update 4 or later).
|
|
|
|
These components are designed to work without requiring any content from the legacy DirectX SDK. For details, see [Where is the DirectX SDK?](https://aka.ms/dxsdk).

## Documentation
|
|
|
|
Documentation is available on the [Microsoft Docs](https://docs.microsoft.com/en-us/windows/desktop/dxmath/directxmath-portal). Additional information can be found on the [project wiki](https://github.com/microsoft/DirectXMath/wiki).
|
|
|
|
## Compiler support
|
|
|
|
Officially the library is supported with Microsoft Visual C++ and clang/LLVM. It should also compile with the Intel C++ compiler, GCC, and MinGW compilers.
|
|
|
|
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](https://github.com/dotnet/corert/blob/master/src/Native/inc/unix/sal.h).
