ATG Samples Content Exporter
----------------------------

Copyright (c) Microsoft Corporation. All rights reserved.

November 2, 2017

The Samples Content Exporter was originally shipped as a sample in the legacy DirectX SDK. It makes
use of the Autodesk FBX SDK to import an FBX file and then export the data as an SDKMESH. The SDKMESH
format is a runtime geometry format supported by the DirectX Tool Kit and DXUT, and is used in the
Windows 8 Store app sample Marble Maze.

The source is written for Visual Studio 2013 Update 5, Visual Studio 2015 Update 3, or Visual Studio 2017.

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>.

    ImportFBX\
        Contains the main entry point for the command-line exporter tool and code for capturing data
        from FBX files.

    ExportObjects\
        Contains a library of support code for the exporter.

    SDKMeshFileWriter\
        Contains a library of code for writing out an .SDKMESH file from data captured as export objects.

    XATGFileWriter
        Contains a library of code for writing out a .XATG file from data captured as export objects.

    DirectXMesh\
        This contains the DirectXMesh geometry processing library that is used instead of legacy D3DX9
        for computing tangent frames and face adjacency.

    DirectXTex\
        This contains the DirectXTex texture processing library that is used instead of legacy D3DX9
        for loading textures, generating mipmaps, and writing DDS files.

        http://go.microsoft.com/fwlink/?LinkId=248926

    UVAtlas
        This contains the UVAtlas isochart library that is used instead of the legacy D3DX9 for creating a
        isochart texture atlas.

BUILD INSTRUCTIONS
------------------

Install the Autodesk FBX SDK 2015.1 or later (latest tested version is 2018.1.1) forWindows VS 2013 and/or VS 2015

    http://autodesk.com/fbx

Ensure the environment variable FBX_SDK is set to point to the Autodesk FBX SDK
(such as "C:\Program Files\Autodesk\FBX\FbxSdk\2018.1.1")

Open the ContentExporter_201?.sln from Visual Studio.

Build the solution

The resulting command-line tool is located under ImportFBX in Debug_201x or Release_201x as ContentExporter.exe

Usage: ContentExporter [options] <filename.fbx>

DISCLAIMER
----------

.SDKMESH has a long-time samples runtime geometry format for Microsoft since the retiring of the
legacy .X file format. It has a number of limitations, and we don't recommend using it as a your
production solution for meshes. It is, however, very useful for samples and itself serves as an
example of such file containers. The documentation on the format can be found in the DirectXMesh
project wiki.

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

* The VS 2015 and later projects do not support building a 32-bit (x86) version of the exporter.
  x64 native (x64) use is wide-spread for content creation tools and provides much greater
  memory flexiblity. The VS 2013 project retains the x86 configuration if needed.

* OpenEXR support for textures is not supported in the VS 2013 build due to limitations in the
  OpenEXR and ZLIB NuGet packages. VS 2013 projects can still build the exporter, but will throw
  an error if you attempt to export an FBX that contains an .exr texture.

* The VS 2017 project uses the VS 2015 version of the Autodesk FBX SDK libraries. VS 2017 C/C++
  Runtime is binary-compatible with VS 2015 so this links successfully.
