The simplex tree is an efficient data structure for representing simplicial complex of any dimension. All of face in simplicial complex store in a trie which nodes are bijection with the face of complex.

Let's start simple example of PySimplex in 3 dimension:

    def insert_childs(self, list_childs):
        if len(list_childs) > 0:
            if not (self.has_child(list_childs[self.HEAD])):
                self.set_childs(list_childs[self.HEAD])
                return
            if self.has_child(list_childs[self.HEAD]):
                list_recursion = []
                for i in range(len(list_childs)):
                    if i <> 0:
                        list_recursion.append(list_childs[i])
                self.get_child(list_childs[self.HEAD]).insert_childs(list_recursion)
        return

• You can create complex with TkInter package(Graphical User Interface) as follow,

• You can import *.obj file with use read_simplex_obj class

in the first textbox enter number of vertex of complex

either can you use the second textbox enter flag complex, or you can use the
third textbox for creation of your complexs

in the forth textbox you can delete face from complex

• Python >= 2.7

PySimplex has no external dependencies outside of the Python standard library.
