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

Copyright (c) Microsoft Corporation. All rights reserved.

November 9, 2016

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 or 2015.

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 2017.0.1) for Windows VS 2013 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\2017.0.1")

Open the ContentExporter_2013.sln or ContentExporter_2015.sln file 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.
