/*
* Shows how to load and display a simple scene from a glTF file
* Note that this isn't a complete glTF loader and only basic functions are shown here
* This means no complex materials, no animations, no skins, etc.
* For details on how glTF 2.0 works, see the official spec at https://github.com/KhronosGroup/glTF/tree/master/specification/2.0
* Shows how to load and display an animated scene from a glTF file using vertex skinning
* See the accompanying README.md for a short tutorial on the data structures and functions required for vertex skinning
*
* Other samples will load models using a dedicated model loader with more features (see base/VulkanglTFModel.hpp)
* For details on how glTF 2.0 works, see the official spec at https://github.com/KhronosGroup/glTF/tree/master/specification/2.0
