libOpenDRIVE is a lightweight, fast C++ library providing OpenDRIVE file parsing and 3D model generation.

It's dependency-free, small and includes a web-based viewer. It can be easily integrated in other projects and can be compiled to a WebAssembly library. A core function is the parsing of OpenDRIVE files and the generation of 3D models. The library targets OpenDRIVE version 1.4.

To build the library simply run:

mkdir build && cd build
cmake ..
make

This also builds an executable to test the library:

./build/test-xodr Viewer/data.xodr

Install emsdk and run the following commands to build the WebAssembly library:

mkdir build && pushd build
emcmake cmake ..
emmake make

emcc -std=c++14 -O3 -Wall -I ../ \
    libOpenDrive.a ../Embind.cpp \
    --bind \
    -s ENVIRONMENT=web \
    -s MODULARIZE=1 \
    -s 'EXPORT_NAME="libOpenDrive"' \
    -s EXPORTED_RUNTIME_METHODS='["cwrap"]' \
    -s FORCE_FILESYSTEM=1 \
    -s ALLOW_MEMORY_GROWTH=1 \
    -o ../Viewer/libOpenDrive.js

popd

To use the included viewer first build the WebAssembly library and then run a webserver in the Viewer/ directory (e.g. python3 -m http.server). Or you can test the viewer online.
