This package contains UVAtlas, a shared source library for creating and packing an
|
|
isochart texture atlas.
|
|
|
|
This code is designed to build with Visual Studio 2015 Update 3, Visual Studio 2017,
|
|
or Visual Studio 2019. 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) / VS 2019 with the Windows 10 October 2018 Update SDK (17763).
|
|
|
|
These components are designed to work without requiring any content from the
|
|
legacy DirectX SDK. For details, see "Where is the DirectX SDK?"

RELEASE NOTES
|
|
-------------
|
|
|
|
* The VS 2017/2019 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.
|
|
|
|
* 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) or VS 2019 to build.
