Installation

Stable

Stable releases of compas_cgal can be installed via conda-forge.

conda create -n cgal -c conda-forge compas compas_cgal --yes
conda activate cgal

Optional

Several examples use COMPAS View2 for visualisation outside of CAD environments. To install compas_view2 in the same environment

conda install compas_view2 --yes

Or everything in one go

conda create -n cgal -c conda-forge compas compas_cgal compas_view2 --yes

Dev Install

A local development version can be set up using a combination of conda and pip. First, clone the compas_cgal repo.

git clone https://github.com/compas-dev/compas_cgal

Create an environment with all the required dependencies.

conda create -n cgal-dev python=3.8 mpir mpfr boost-cpp eigen=3.3 cgal-cpp=5.2 pybind11 compas compas_view2 --yes

conda create -n cgal-dev python=3.8 mpir mpfr boost-cpp eigen=3.3 cgal-cpp=5.2 pybind11 compas compas_view2 --yes

Activate the environment.

conda activate cgal-dev

Change to the root folder of the compas_cgal repo.

cd compas_cgal

And compile the code while creating an editable install of the python wrapper using setuptools.

pip install -e .

To add your c++ module to the wrapper, and potentially exclude some of the existing modules during its development, modify the list of extension modules in the setup.py file.

ext_modules = [
    Extension(
        'compas_cgal._cgal',
        sorted([
            'src/compas_cgal.cpp',
            'src/compas.cpp',
            'src/meshing.cpp',
            'src/booleans.cpp',
            'src/slicer.cpp',
            'src/intersections.cpp',
            'src/measure.cpp',
        ]),
        include_dirs=[
            './include',
            get_eigen_include(),
            get_pybind_include()
        ],
        library_dirs=[
            get_library_dirs(),
        ],
        libraries=['mpfr', 'gmp'],
        language='c++'
    ),
]
