README.md

glTF is the runtime asset format for WebGL, OpenGL ES, and OpenGL.

glTF is a draft specification, it may change before ratification. Everyone is encouraged to provide feedback on the specification and contribute to the open-source converter. Please create issues with your feedback.

Specification

glTF Specification 1.0

Converter

glTF is an open-source command-line pipeline tool that converts FBX file (and any file format that FBX can read such as obj, collada, ...) to glTF.

FBX importer/exporter plug-in

IO-glTF is an open-source FBX importer/exporter plug-in that converts FBX file (and any file format that FBX can read such as obj, collada, ...) to glTF.
This plug-in can be used by any FBX based application to import/export glTF files.

Dependencies

This sample is dependent of the following 3rd party extension:

  • The Casablanca C++ RESTful SDK - version 2.4.0.1

  • The FBX C++ SDK - version 2015.1

  • For building on Mac OSX, and Linux, you also need cmake which is also required for the Casablanca C++ RESTful SDK.
    However, Casablanca requires version 2.8 (or later), while the glTF converter is setup to use version 3.1, you may install version 3.1 or change the cmake files header back to 2.8.

Build the solution

Windows

Required: Visual Studio 2013 (should work with Visual Studio 2012 too, but not tested)

  1. Download and install the FBX SDK

  2. Clone or download the FBX-glTF source code

  3. Load the glTF.sln solution file in Visual Studio 2013

  4. Optional: if you did not install FBX at the standard location or use a version different from 2015.1, open the solution Property Manager and edit the User Macro FBX_SDK to point to the root of your FBX SDK. Another way is to edit the Fbx.props file and manually change the path before step 2.

  5. Build the FBX-glTF solution. NuGet will install 'casablanca' for you upon building.

Mac OSX

Required: Mac OSX Maverick or Yosemite, Xcode 6.1.1

  1. Download and install the FBX SDK

  2. Clone or download the FBX-glTF source code

  3. Download and compile 'casablanca' on your machine. Instructions here

  4. Install ‘casablanca’ on your system by running ‘sudo make install’

  5. Recommended: Create a folder with the name you want, and go in that directory

  6. Optional: Copy the CMakeConfigExample.txt file and rename it as CMakeCache.txt in your build folder, and edit the FBX path entry. That will avoid you to type the parameters below.

  7. Execute:

    a. For a release build: cmake .. -DCMAKE_BUILD_TYPE=Release -DFBX_SDK=<path to FBX>

    b. For a debug build: cmake .. -DCMAKE_BUILD_TYPE=Debug -DFBX_SDK=<path to FBX>

    or simply ‘cmake ..’ if you followed step 6.

Note: on Mac OSX, the FBX SDK installs by default in /Applications/Autodesk/FBX SDK/2015.1

Linux

Required: gcc 4.8+ (tested on Ubuntu Linux 14.04 Desktop)

  1. Download and install the FBX SDK

  2. Clone or download the FBX-glTF source code

  3. Download and compile 'casablanca' on your machine. Instructions here

  4. Install ‘casablanca’ on your system by running ‘sudo make install’

  5. Recommended: Create a folder with the name you want, and go in that directory

  6. Optional: Copy the CMakeConfigExample.txt file and rename it as CMakeCache.txt in your build folder, and edit the FBX path entry. That will avoid you to type the parameters below.

  7. Execute:

    a. For a release build: cmake .. -DCMAKE_BUILD_TYPE=Release -DFBX_SDK=<path to FBX>

    b. For a debug build: cmake .. -DCMAKE_BUILD_TYPE=Debug -DFBX_SDK=<path to FBX>

    or simply ‘cmake ..’ if you followed step 6.

Usage Instructions

For Windows, the files will be located in FBX-glTF\x64\Release or FBX-glTF\x64\Debug

For both Mac OXS and Linux, the files will be located in FBX-glTF/<your cmake folder>/Release or FBX-glTF//Debug

Usage: glTF [-h] [-v] [-t] [-l] [-e] [-o ] -f <input file>

-f/--file        - file to convert to glTF [string] 
-o/--output      - path of output directory [string]
-n/--name        - override the scene name [string]
-c/--copy        - copy all media to the target directory (cannot be combined with --embed)
-e/--embed       - embed all resources as Data URIs (cannot be combined with --copy)
-h/--help        - this message
-v/--version     - version

Typical command:

glTF -f MyFBXorDAEfile -o MyOutputDirectory -n NewName -c

Example:

cd FBX-glTF\models\duck
glTF -f duck.fbx -o ..\..\three.js\models\duck -n duck -c
cd ..\au
glTF -f au.fbx -o ..\..\three.js\models\au -c
glTF -f au3.fbx -o ..\..\three.js\models\au3 -e

Viewing results using Three.js

  1. Install Node.js on your computer

  2. Open a node terminal

  3. Go in directory FBX-glTF/Three.js

  4. Execute: npm install

  5. Execute: node serve.js

  6. Launch your internet favourite browser and browse to http://localhost
