----------------------------------- UVAtlas - isochart texture atlasing ----------------------------------- Copyright (c) Microsoft Corporation. All rights reserved. April 23, 2018 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 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 (15.5 update) or later with the Windows 10 Fall Creators Update SDK (16299). 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>.

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 deleting /permissive- from the project files which is found in the <AdditionalOptions> element. --------------- RELEASE HISTORY --------------- April 23, 2018 Code and project cleanup February 7, 2018 Minor code update December 13, 2017 Updated for VS 2017 15.5 update warnings November 1, 2017 VS 2017 updated for Windows 10 Fall Creators Update SDK (16299) Removed UVAtlas_2017.vcxproj as redundant in favor of UVAtlas_2017_Win10.vcxproj September 22, 2017 Updated for VS 2017 15.3 update /permissive- changes uvatlas: added -flist option July 28, 2017 Code cleanup April 24, 2017 VS 2017 project updates April 8, 2017 VS 2017 updated for Windows Creators Update SDK (15063) Minor code cleanup January 31, 2017 uvatlas command-line tool: Updated for latest DirectXMesh uvatlas command-line tool: optional OpenEXR support VS 2017 RC projects added Minor code cleanup September 14, 2016 uvatlas command-line tool: added wildcard support for input filename and optional -r switch for recursive search uvatlas command-line tool -it switch now supports HDR (RGBE Radiance) texture files (requires DirectXTex September 2016 release to build) Code cleanup August 2, 2016 Updated for VS 2015 Update 3 and Windows 10 SDK (14393) June 27, 2016 Code cleanup April 26, 2016 Retired VS 2012 projects and obsolete adapter code Minor code cleanup November 30, 2015 uvatlas command-line tool updated with -flipv and -flipz switches; removed -fliptc Updated for VS 2015 Update 1 and Windows 10 SDK (10586) October 30, 2015 Minor code cleanup July 29, 2015 Updated for VS 2015 and Windows 10 SDK RTM Retired VS 2010 and Windows 8.0 Store projects June 18, 2015 Fixed bugs with handling of E_ABORT from user callback Added ESC to abort to uvatlas sample April 9, 2015 Added projects for Windows apps Technical Preview Fixes for potential divide-by-zero cases Fix for memory allocation problem Added error detection for invalid partitioning uvatlas: fix when importing from .vbo Minor code cleanup November 12, 2014 Original release
