Meshconvert tool
DirectXMesh is also available from the NuGet Gallery:
- Windows desktop app using VS 2019 or VS 2022
- Windows desktop app using VS 2019 or VS 2022 for Windows 10 / DX 12
- Universal Windows Platform apps using VS 2019 or VS 2022
DirectXMesh has a vcpkg installation port as well.
See this post for a complete listing of D3DX equivalents.
