The 2Dskeleton executable is implemented in C++ and computes the L infinity Voronoi diagram and cube skeleton of orthogonal polygons. The bash script scaleCubeSkeleton2D.sh implements the 2D scale cube skeleton and the treatment of PPM images. It also uses the Marc Vigo Orto-brep Python software to extract the boundary of PPM images, and the Daniel López BoxUnion3D C++ sofware to compute the union of rectangles. Daniel López also contributed to the ScaleCubeSkeleton2D software.
