gltfpp is a glTF 2.0 loader written in C++14 targeting desktop platforms and WebAssembly with a focus on ease of use, type safety and extensibility.
WORK IN PROGRESS! This library is not finished yet.
- gcc >= 6 or clang >= 3.6
- CMake >= 3.2
- Boost >= 1.61
Boost.Outcome, GSL, nlohmann/json, better-enums and Catch are included via git submodules.
gltfpp is header only and therefore does not require a build step. Make sure you have all dependencies set up correctly if you only copy the directory.
When using clang, modules can by enabled by passing -DGLTFPP_ENABLE_MODULES=1 to CMake. This should speed up the compilation, however this is experimental and has only been tested with clang 5.0 snapshots so far.
Install emscripten, then invoke CMake via emconfigure:
emconfigure cmake .. [-GNinja] [-DGLTFPP_WEBASSEMBLY=1] # Default is wasm instead of asm.js
Compiling to WebAssembly requires binaryen. Note that this library does not export anything, so you can't use it in the browser yet.
By passing the flag -DGLTFPP_AS_HTML=1, emscripten generates a html page with a terminal emulator for each executable (read: the unit test runner).
Run them in your browser (requires WebAssembly support)
mkdir build && cd build
cmake .. -DGLTFPP_BUILD_TESTS=1 [-GNinja]
make gltfpp_test # Or ninja
ctest .
To run the fuzzer, build the fuzz target and execute it via test/fuzz. There is no meaningful dictionary for efficient fuzzing yet.
- Parsing infrastructure (trivial properties can be parsed simply by declaring their fields)
- Finished properties:
Asset,Buffer(only data uris),BufferView - Build system support for Emscripten
- deserialization of external buffer data (GLB)
- Networking (HTTP on desktop, XHR on WebAssembly), asynchronous loading
- Proper documentation
- out of tree extensions?
- a small viewer based on the loader
- Export functions to the web browser
