Add feature to store original JSON string for extras and extensions(for user-specific JSON parsing). # Fixes 215 Fix some glTF object(e.g. Skin) does not have extras and/or extensions property.
TinyGLTF is a header only C++11 glTF 2.0 https://github.com/KhronosGroup/glTF library.
TinyGLTF uses Niels Lohmann's json library(https://github.com/nlohmann/json), so now it requires C++11 compiler. If you are looking for old, C++03 version, please use devel-picojson branch.
json.hpp..bin file.In extension(ExtensionMap), JSON number value is parsed as int or float(number) and stored as tinygltf::Value object. If you want a floating point value from tinygltf::Value, use GetNumberAsDouble() method.
IsNumber() returns true if the underlying value is an int value or a floating point value.

TinyGLTF uses the following third party libraries.
Copy stb_image.h, stb_image_write.h, json.hpp and tiny_gltf.h to your project.
// Define these only in *one* .cc file. #define TINYGLTF_IMPLEMENTATION #define STB_IMAGE_IMPLEMENTATION #define STB_IMAGE_WRITE_IMPLEMENTATION // #define TINYGLTF_NOEXCEPTION // optional. disable exception handling. #include "tiny_gltf.h" using namespace tinygltf; Model model; TinyGLTF loader; std::string err; std::string warn; bool ret = loader.LoadASCIIFromFile(&model, &err, &warn, argv[1]); //bool ret = loader.LoadBinaryFromFile(&model, &err, &warn, argv[1]); // for binary glTF(.glb) if (!warn.empty()) { printf("Warn: %s\n", warn.c_str()); } if (!err.empty()) { printf("Err: %s\n", err.c_str()); } if (!ret) { printf("Failed to parse glTF\n"); return -1; }
TINYGLTF_NOEXCEPTION : Disable C++ exception in JSON parsing. You can use -fno-exceptions or by defining the symbol JSON_NOEXCEPTION and TINYGLTF_NOEXCEPTION to fully remove C++ exception codes when compiling TinyGLTF.TINYGLTF_NO_STB_IMAGE : Do not load images with stb_image. Instead use TinyGLTF::SetImageLoader(LoadimageDataFunction LoadImageData, void *user_data) to set a callback for loading images.TINYGLTF_NO_STB_IMAGE_WRITE : Do not write images with stb_image_write. Instead use TinyGLTF::SetImageWriter(WriteimageDataFunction WriteImageData, void *user_data) to set a callback for writing images.TINYGLTF_NO_EXTERNAL_IMAGE : Do not try to load external image file. This option would be helpful if you do not want to load image files during glTF parsing.TINYGLTF_ANDROID_LOAD_FROM_ASSETS: Load all files from packaged app assets instead of the regular file system. Note: You must pass a valid asset manager from your android app to tinygltf::asset_manager beforehand.TINYGLTF_ENABLE_DRACO: Enable Draco compression. User must provide include path and link correspnding libraries in your project file.TINYGLTF_NO_INCLUDE_JSON : Disable including json.hpp from within tiny_gltf.h because it has been already included before or you want to include it using custom path before including tiny_gltf.h.TINYGLTF_NO_INCLUDE_STB_IMAGE : Disable including stb_image.h from within tiny_gltf.h because it has been already included before or you want to include it using custom path before including tiny_gltf.h.TINYGLTF_NO_INCLUDE_STB_IMAGE_WRITE : Disable including stb_image_write.h from within tiny_gltf.h because it has been already included before or you want to include it using custom path before including tiny_gltf.h.TINYGLTF_USE_RAPIDJSON : Use RapidJSON as a JSON parser/serializer. RapidJSON files are not included in TinyGLTF repo. Please set an include path to RapidJSON if you enable this featrure.TINYGLTF_USE_CPP14 : Use C++14 feature(requires C++14 compiler). This may give better performance than C++11.Python 2.6 or 2.7 required. Git clone https://github.com/KhronosGroup/glTF-Sample-Models to your local dir.
After building loader_example, edit test_runner.py, then,
$ python test_runner.py
$ cd tests $ make $ ./tester $ ./tester_noexcept
