Bug in REGULAR property of a polyhedral fan

Dear all, there is a bug in computing the REGULAR property of a polyhedral fan. If I create the following fan, I get a negative result for REGULAR, however it is the normal fan of a polytope. Best, Sebastian fan > $rays=[[1,0,0,0],[0,1,0,0],[0,0,1,0],[1,0,-1,-1],[-1,-1,0,0]]; fan > $cones=[[1,2,3,5]...

Polymake with Perl 5.18.0

Re: Visual in callable library

Turns out I can, doing it like this: VoidCallPolymakeFunction( "sketch", p->CallPolymakeMethod("VISUAL"), PolymakeOptions("File", "sketchtest.sk") ); I think I can life with this for now, but I would really prefer if it is possible to store the visual objects,...

Re: Visual in callable library

I want to pass the result to the sketch-method.
I think I can do this in one command, using VoidCallPolymakeMethod, but it might be a bit long, but I will try this.

Visual in callable library

Dear all, when trying to save the output of the VISUAL-Method in C++, I constantly get errors ("input value is not an Object"). Is VISUAL not returning an perl::Object? A short piece of code is attached, where you can see the error. Best wishes, Sebas Part 1: visualtest.cc #include <polyma...

Re: Polymake does not work in Perl 5.16

Nevermind, I found that it is already fixed in the svn-version.

Polymake does not work in Perl 5.16

Hey everyone, I just tried to install polymake on a system with a new perl version, perl 5, version 16, subversion 2. Anyway, it does not run on the system. Compiling works just fine, but when starting polymake it says it cannot find the symbol Perl_mod. /usr/bin/perl: symbol lookup error: /usr/loca...

Re: RelInt Lattice Points

Thank you for the quick reply. The last method seems to do what I want, as it also computes the relative interior lattice points of an not full dimensional lattice polytope. $p = new LatticePolytope(POINTS=>[[1,1,1,1],[1,-1,-1,1],[1,-1,1,1],[1,1,-1,1]]); print $p->INTERIOR_LATTICE_POINTS; 1 0 0 1 Do...

RelInt Lattice Points

Hello,

is there a possibility to compute a ( arbitrary ) lattice point in the relative interior of a polytope, if such a point exists? The property REL_INT_POINT does not return a lattice point, not even from a LatticePolytope.

Thank you very much for your help,

Sebastian
