/**
* Simple Evas example illustrating import/export of .ply format.
*
* Read meshes from "tested_man_all_with_mods.ply", "tested_man_only_geometry.ply" and "tested_man_without_UVs.ply".
* After that cheange some properties of material.
* After that save material to "saved_man.mtl"
* and geometry to "saved_man_all_with_mods.ply", "saved_man_only_geometry.ply" and "saved_man_without_UVs.ply".
*
* @verbatim
* gcc -o evas-3d-ply evas-3d-ply.c `pkg-config --libs --cflags efl evas ecore ecore-evas eo`
