DirectXMesh geometry processing library

Copyright (c) Microsoft Corporation.

April 6, 2021

This package contains DirectXMesh, a shared source library for performing various geometry content processing operations including generating normals and tangent frames, triangle adjacency computations, vertex cache optimization, and meshlet generation.

This code is designed to build with Visual Studio 2017 (15.9), Visual Studio 2019, or clang for Windows v9 or later. It is recommended that you make use of the Windows 10 May 2020 Update SDK (19041).

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


Documentation is available on the GitHub wiki.


All content and source code for this package are subject to the terms of the MIT License.

Release Notes

  • 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 is consistent with Direct3D 12's use of the DEFINE_ENUM_FLAG_OPERATORS macro. 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: CNORM_DEFAULT, VALIDATE_DEFAULT, or MESHLET_DEFAULT.

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

  • The UWP projects and the VS 2019 Win10 classic desktop project include configurations for the ARM64 platform. These require VS 2017 (15.9 update) or VS 2019 to build, with the ARM64 toolset installed.
