Sage allows you to create point configurations and to compute the example we have seen in class.
Here are some basic operations.
{{{id=1| # create a point configuration PC = PointConfiguration([(0,0),(3,0),(0,3),(3,3),(1,1)]) PC /// }}} {{{id=3| # list the triangulations T = PC.triangulations_list() T /// }}} {{{id=4| # plot a triangulation T[0].plot() /// }}} {{{id=5| # list the circuits (C+, C0, C-) PC.circuits() /// }}} {{{id=6| # compute the convex hull PC.convex_hull() /// }}}Take the exercise sheets of Monday and see if you can reproduce the computation and obtain the same results.
{{{id=7| /// }}}
