cgltf - a single-file glTF 2.0 parser written in C99.

Building: Include this file where you need the struct and function declarations. Have exactly one source file where you define CGLTF_IMPLEMENTATION before including this file to get the function definitions.
Reference: cgltf_result cgltf_parse(const cgltf_options*, const void*, cgltf_size, cgltf_data**) parses both glTF and GLB data. If this function returns cgltf_result_success, you have to call cgltf_free() on the created cgltf_data* variable. Note that contents of external files for buffers and images are not automatically loaded. You'll need to read these files yourself using URIs in the cgltf_data structure.
cgltf_options is the struct passed to cgltf_parse() to control parts of the parsing process. You can use it to force the file type and provide memory allocation as well as file operation callbacks. Should be zero-initialized to trigger default behavior.
cgltf_data is the struct allocated and filled by cgltf_parse(). It generally mirrors the glTF format as described by the spec (see https://github.com/KhronosGroup/glTF/tree/master/specification/2.0).
void cgltf_free(cgltf_data*) frees the allocated cgltf_data variable.
cgltf_result cgltf_load_buffers(const cgltf_options*, cgltf_data*, const char* gltf_path) can be optionally called to open and read buffer files using the FILE* APIs. The gltf_path argument is the path to the original glTF file, which allows the parser to resolve the path to buffer files.
cgltf_result cgltf_load_buffer_base64(const cgltf_options* options, cgltf_size size, const char* base64, void** out_data) decodes base64-encoded data content. Used internally by cgltf_load_buffers(). This is useful when decoding data URIs in images.
cgltf_result cgltf_parse_file(const cgltf_options* options, const char* path, cgltf_data** out_data) can be used to open the given file using FILE* APIs and parse the data using cgltf_parse().
cgltf_result cgltf_validate(cgltf_data*) can be used to do additional checks to make sure the parsed glTF data is valid.
cgltf_node_transform_local converts the translation / rotation / scale properties of a node into a mat4.
cgltf_node_transform_world calls cgltf_node_transform_local on every ancestor in order to compute the root-to-node transformation.
cgltf_accessor_unpack_floats reads in the data from an accessor, applies sparse data (if any), and converts them to floating point. Assumes that cgltf_load_buffers has already been called. By passing null for the output pointer, users can find out how many floats are required in the output buffer.
cgltf_num_components is a tiny utility that tells you the dimensionality of a certain accessor type. This can be used before cgltf_accessor_unpack_floats to help allocate the necessary amount of memory.
cgltf_accessor_read_float reads a certain element from a non-sparse accessor and converts it to floating point, assuming that cgltf_load_buffers has already been called. The passed-in element size is the number of floats in the output buffer, which should be in the range [1, 16]. Returns false if the passed-in element_size is too small, or if the accessor is sparse.
cgltf_accessor_read_uint is similar to its floating-point counterpart, but limited to reading vector types and does not support matrix types. The passed-in element size is the number of uints in the output buffer, which should be in the range [1, 4]. Returns false if the passed-in element_size is too small, or if the accessor is sparse.
cgltf_accessor_read_index is similar to its floating-point counterpart, but it returns size_t and only works with single-component data types.
cgltf_result cgltf_copy_extras_json(const cgltf_data*, const cgltf_extras*, char* dest, cgltf_size* dest_size) allows users to retrieve the "extras" data that can be attached to many glTF objects (which can be arbitrary JSON data). The cgltf_extras struct stores the offsets of the start and end of the extras JSON data as it appears in the complete glTF JSON data. This function copies the extras data into the provided buffer. If dest is NULL, the length of the data is written into dest_size. You can then parse this data using your own JSON parser or, if you've included the cgltf implementation using the integrated JSMN JSON parser.
