TinyGLTFLoader is a header only C++ glTF https://github.com/KhronosGroup/glTF parsing library

Build Status

Build status

Features

  • Portable C++. C++-03 with STL dependency only.
  • Moderate parsing time and memory consumption.
  • glTF specification v1.0.0
  • Buffers
    • [x] Parse BASE64 encoded embedded buffer fata(DataURI).
    • [x] Load .bin file.
  • Image(Using stb_image)
    • [x] Parse BASE64 encoded embedded image fata(DataURI).
    • [x] Load external image file.
    • [x] PNG(8bit only)
    • [x] JPEG(8bit only)
    • [x] BMP
    • [x] GIF

Examples

  • glview : Simple glTF geometry viewer.
  • writer : Simple glTF writer(serialize tinygltf::Scene class)
  • alembic_to_gltf : Simple Alembic to glTF converter.
  • cyhair_to_gltf : Simple CyHair(hair curves) to glTF converter.

TODOs

  • [ ] Write C++ code generator from json schema for robust parsing.
  • [ ] Support multiple scenes in .gltf
  • [ ] Parse skin
  • [ ] Compression/decompression(Open3DGC, etc)

Build and example

Copy stb_image.h, picojson.h and tiny_gltf_loader.h to your project.

// Define these only in *one* .cc file.
#define TINYGLTF_LOADER_IMPLEMENTATION
#define STB_IMAGE_IMPLEMENTATION
#include "tiny_gltf_loader.h"

using namespace tinygltf;

Scene scene; 
TinyGLTFLoader loader;
std::string err;
  
bool ret = loader.LoadASCIIFromFile(scene, err, argv[1]);
//bool ret = loader.LoadBinaryFromFile(scene, err, argv[1]); // for binary glTF(.glb) 
if (!err.empty()) {
  printf("Err: %s\n", err.c_str());
}

if (!ret) {
  printf("Failed to parse glTF\n");
  return -1;
}

Running tests.

Setup

Python 2.6 or 2.7 required. Git clone https://github.com/KhronosGroup/glTF-Sample-Models to your local dir.

Run test

After building loader_example, edit test_runner.py, then,

$ python test_runner.py
