Semi-Discrete Optimal Transport in 2d

Installation:

0. Install Dependencies:

conda install -c conda-forge cgal cmake

1. Clone sdot2d and dependent repositories

git clone --recurse-submodules git@github.com:mparno/sdot2d.git

2. Run CMake to configure sdot2d

cd sdot2d
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=<Some/Install/Dir> ..

where you should replace <Some/Install/Dir> with the location where you want to install the SDOT2d library, for example ~/Installations/SDOT_INSTALL.

You can also tell CMake where to look for GTest using the following command instead:

cmake -DCMAKE_INSTALL_PREFIX=<Some/Install/Dir> -DSDOT_GTEST_DIR=<gtest/install/dir> ..

The gtest/install/dir should be the folder that contains the include and lib folders where GTest has been installed.

3. Build SDOT (including optional tests)

make -j4 install

4. (Optional) Run the tests

make test

or, to run just the unit tests

./RunUnitTests

5. Add the SDOT paths to your environment variables:

OSX:

export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:<Some/Install/Dir>/lib
export PYTHONPATH=$PYTHONPATH:<Some/Install/Dir>/lib:<Some/Install/Dir>/lib/python/

Linux:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:<Some/Install/Dir>/lib
export PYTHONPATH=$PYTHONPATH:<Some/Install/Dir>/lib:<Some/Install/Dir>/lib/python/

Examples:

Try running the random points in a rectangle example

cd sdot2d/examples/python
python RandomRectangle.py
