Using a C++ glTF loader to get the model data

An uncomplicated way to load a glTF model into a structured data model can be achieved by using a glTF loader library. For this book, we will use the tinygltf library.

The repository for the project is available at GitHub: https://github.com/syoyo/tinygltf.

We need to add a couple of files to our project. Create a new folder called tinygltf, download the following files, and move them into the new folder:

• tiny_gltf.h
• tiny_gltf.cc
• json.hpp

The tiny_gltf.h file contains the glTF loader implementation itself; this is the file we will have to include to the classes loading the model file. The next file on the list, tiny_gltf.cc, has some additional C-style #define directives that are required for the loader. The last file, json.hpp, is required to read and write JSON files.

In addition to these three files, we need to get two other files. Download these two files to the include folder:

• stb_image.h
