This is a (very hacky) comparison of various polygon clipping algorithms.
shut up and take me to the damn thing
The 'ground truth' to compare against was approximated via a rasterization of the polygons (using inkscape) followed by the boolean operations (using graphicsmagick)
Various implementations try to do the boolean operations on the polygons, the resulting polygons are also translated to svg, rasterized with inkscape and those results are finally compared on a pixel basis, using various metrics and graphicsmagick.
dissection contains a small viewer for the results
unisamples contain the fixtures as well as conversion tools
magick contains the 'ground truth' build using graphicsmagick

this is far from packed for re-use, but if you insist, the main dependencies should be node, graphicsmagick and inkscape
graphicsmagick can be downloaded (source) and compiled into a set of command line utilities. See http://www.graphicsmagick.org/README.html
inkscape can be downloaded and installed. See https://inkscape.org
install LTS versions of npm and node.js
now run these commands inside the poly-bool-comparison directory
npm install
npm run setup
to re-run everything try running ./run... good luck ;)
to update a single algorithm run ./run <dirname>
