Positive Regions:—,Negative Regions:—
Click a flip to apply it. Onlybridgeandcornerflips are enabled. Border color:■M-curve ■more regions ■fewer regions ■bridge/same ■other
Click a vertex to flip its sign. Border color uses the same scheme as edge flips.
Save the current patchwork to a.pcomfile, or load one from disk. You can also drag and drop a.pcomfile onto the canvas.
Patchworking GUI
This is a graphical user interface for exploring Viro's patchworking construction. It is build on top of the C++ library libisotopy and was inspired by Johannes Rau's Combinatorial Patchworking Tool.
This tool is actively being developed by Marcel Wack.
