This group is for discussing opencamlib, a GPL-licensed C++ library (with python bindings), of computational geometry algorithms for computer aided manufacturing (CAM). Code is hosted at github: https://github.com/aewallin/opencamlib (cutter projection and other toolpath-generation algorithms) https://github.com/aewallin/openvoronoi (voronoi diagram code for 2D operations) https://github.com/aewallin/cutsim (cutting-simulation for toolpath verification and visualization)
