Description
#22701 implemented setting up a polyhedron from both Vrep and Hrep for the backend field.
There are plans to allow the same for polymake #26368 and with #28639 at hand we can do the same for normaliz.
So it makes sense to set up a general framework for initializing from Vrep and Hrep. This ticket does this (or rather moves what was done in #22701 accordingly).
If a backend implements the method _init_from_Vrepresentation_and_Hrepresentation
, then the initialization of Polyhedron_base
may use it if Vrep_minimal
and Hrep_minimal
is both set to true.
This option will not be exposed in the function Polyhedron
, as a user should really know what they are doing.
Also the method _element_constructor_polyhedron
of Polyhedra_base
sets up the new polyhedron from both representations, if self.Element
has the method _init_from_Vrepresentation_and_Hrepresentation
.
