Single-file/stb-style C glTF loader

#include "cgltf.h"

void* buf; /* Pointer to glb or gltf file data */
size_t size; /* Size of the file data */

cgltf_options options = {0};
cgltf_data data;
cgltf_result result = cgltf_parse(&options, buf, size, &data);
if (result == cgltf_result_success)
{
	/* TODO make awesome stuff */
	cgltf_free(&data);
}

cgltf supports this:

• glTF 2.0
• glb (binary files) and gltf (JSON files)
• meshes (including accessors, buffer views, buffers)

cgltf does not yet support this:

• animations
• scenes and nodes
• materials
• any extensions (like Draco, for example)

The easiest approach is to integrate the cgltf.h header file into your project. If you are unfamiliar with single-file C libraries (also known as stb-style libraries), this is how it goes:

1. Include cgltf.h where you need the functionality.
2. Have exactly one source file that defines CGLTF_IMPLEMENTATIONbefore including cgltf.h.
3. Use the cgltf functions as described above.

For testing, there is a CMake file in test test/ folder.

Everyone is welcome to contribute to the library. If you find any problems, you can submit them using GitHub's issue system. If you want to contribute code, you should fork the project and then send a pull request.

Basically none.

C headers being used:

#include <stdint.h>
#include <string.h>
#include <stdlib.h>

Note, this library integrates the JSMN JSON parser into its source.

There is a Python script in the test/ folder that retrieves the glTF sample files from the glTF-Sample-Models repository and runs the library against all gltf and glb files in there.
