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_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
.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
