*
* raylib [models] example - OBJ models viewer
* raylib [models] example - Models loading
*
* This example has been created using raylib 2.0 (www.raylib.com)
* raylib supports multiple models file formats:
*
* - OBJ > Text file, must include vertex position-texcoords-normals information,
* if files references some .mtl materials file, it will be loaded (or try to)
* - GLTF > Modern text/binary file format, includes lot of information and it could
* also reference external files, raylib will try loading mesh and materials data
* - IQM > Binary file format including mesh vertex data but also animation data,
* raylib can load .iqm animations.
*
* This example has been created using raylib 2.6 (www.raylib.com)
* raylib is licensed under an unmodified zlib/libpng license (View raylib.h for details)
