DIRECTX MESH LIBRARY (DirectXMesh)
------------------------------------

Copyright (c) Microsoft Corporation. All rights reserved.

February 7, 2019

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

This code is designed to build with Visual Studio 2015 Update 3 or Visual Studio 2017.
It is recommended that you make use of VS 2015 Update 3, Windows Tools 1.4.1, and the
Windows 10 Anniversary Update SDK (14393) -or- VS 2017 (15.9 update) with the
Windows 10 October 2018 Update SDK (17763).

These components are designed to work without requiring any content from the DirectX SDK. For details,
see "Where is the DirectX SDK?" <http://msdn.microsoft.com/en-us/library/ee663275.aspx>.

DirectXMesh\
    This contains the DirectXMesh library.

    Note that the majority of the header files here are intended for internal implementation
    of the library only (DirectXMeshP.h and scoped.h). Only DirectXMesh.h is meant as a
    'public' header for the library.

Utilities\
    This contains helper code related to mesh processing that is not general enough to be
    part of the DirectXMesh library.

         WaveFrontReader.h - Contains a simple C++ class for reading mesh data from a WaveFront OBJ file.

Meshconvert\
    This DirectXMesh sample is an implementation of the "meshconvert" command-line texture utility
    from the DirectX SDK utilizing DirectXMesh rather than D3DX.

    Note this tool does not support legacy .X files, but can export CMO, SDKMESH, and VBO files.

RELEASE NOTES
-------------

* The VS 2017 projects make use of /permissive- for improved C++ standard conformance. Use of a Windows 10 SDK prior to
  the Fall Creators Update (16299) or an Xbox One XDK prior to June 2017 QFE 4 may result in failures due to problems
  with the system headers. You can work around these by disabling this switch in the project files which is found
  in the <ConformanceMode> elements. In some cases, you can add '/Zc:twoPhase-' to <AdditionalOptions> instead of
  completely disabling conformance mode.

* The VS 2017 projects require the 15.5 update or later. For UWP and Win32 classic desktop projects with the 15.5 -
  15.7 updates, you need to install the standalone Windows 10 SDK (17763) which is otherwise included in the 15.8.6 or
  later update. Older VS 2017 updates will fail to load the projects due to use of the <ConformanceMode> element.
  If using the 15.5 or 15.6 updates, you will see "warning D9002: ignoring unknown option '/Zc:__cplusplus'" because
  this switch isn't supported until 15.7. It is safe to ignore this warning, or you can edit the project files
  <AdditionalOptions> elements.

* The UWP projects include configurations for the ARM64 platform. These require VS 2017 (15.9 update) to build.
