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_accessor_unpack_indices reads in the index data from an accessor. Assumes that cgltf_load_buffers has already been called. By passing null for the output pointer, users can find out how many indices are required in the output buffer. Returns 0 if the accessor is sparse or if the output component size is less than the accessor's component size.
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_component_size and cgltf_calc_size exist for similar purposes.
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_copy_extras_json allows users to retrieve the "extras" data that can be attached to many glTF objects (which can be arbitrary JSON data). This is a legacy function, consider using cgltf_extras::data directly instead. You can parse this data using your own JSON parser or, if you've included the cgltf implementation using the integrated JSMN JSON parser.
