Graphical User Interface
To use SnapPea 3.0’s Graphical User Interface, start your python interpreter, passing it the file SnapPeaGUI.py. On Unix systems this is trivially easy: just go to the SnapPeaPython directory (which you should have already downloaded, as explained on installation page) and type python SnapPeaGUI.py.
You get a main window offering you the choice of reading a manifold from a file (SnapPea 2.x files work fine) or loading a manifold from the Cusped Census. (A later release will include the Closed Census manifolds as well.)
Each manifold you open gets its own window. The View menu lets you select which features to view. Many features are already implemented; those which are not will be available in later releases.
To investigate large classes of manifolds, use SnapPea 3.0’s scripting interface.up
