Re: Visualization bug(?) in Polymake 4.6

Sorry for the late reply, I just wanted to say that Benjamin's suggestion helped. I couldn't figure out how to run code in the javascript console in Firefox, but adding his code to the generated html file helped: if ( THREE.WEBGL.isWebGLAvailable() ) { render(); + for (var i=0; i<scene.children.leng...

Building polymake 4.6 on Ubuntu 20.04, linking problems with flint

I need some help to resolve following error when trying to compile polymake 4.6 on Ubuntu 20.04.3, does anybody know what may be the cause of it? ren@thinkpad:~/polymake$ make ninja -C build/Opt all ninja: Entering directory `build/Opt' [1/3] LINK /home/ren/polymake/build/Opt/perlx/5.30.0/x86_64-lin...

Visualization bug(?) in Polymake 4.6

In Polymake 4.6, the following visualization (using threejs) produces 2-faces that appear/disappear depending on the angle of view. In Polymake 4.3 everything is visualized correctly: application "tropical"; $f1 = toTropicalPolynomial("max(1*x+2*y+3*z+4*w,3*x+3*y+3*z+1*w,2*x+1*y+5*z+2...

Stable intersection of tropical hypersurfaces

In the following example, the stable intersection T12345 is empty even though I think it should not be: application "tropical"; $f1 = toTropicalPolynomial("min(33+x1,72+x2)",qw( w x1 x2 x3 x4 x5 x6 x7 x8 x9 x10 x11 x12 x13 x14 x15 x16 x17 x18 x19 )); $f2 = toTropicalPolynomial(&q...

Re: Computing one interior lattice points of possibly unbounded polytopes

That is wonderful! This will be so incredibly useful when trying to get easiest possible lifts!!! But is this also available for polytopes? Because I am not looking for any lift of a given subdivision, but one whose dual tropical curve T has edges of certain prescribed lengths. (This is because we w...

Computing one interior lattice points of possibly unbounded polytopes

Sorry for the possibly stupid question, but is there a fast way to compute a single interior lattice point of a possibly unbounded polyhedron in polymake? Preferably of small (ideally minimal) L1-norm. I know that I can 1. make it bounded by intersecting it with a dilated cube, 2. enumerate all inte...

Computing secondary fans

Can somebody please explain to me how to compute the secondary fan of [0,3]x[0,3] (i.e., the moduli space of tropical plane curves of bidegree (3,3))? The following code only produces an empty fan for me: $M33 = new Matrix([[0,0],[1,0],[2,0],[3,0], [0,1],[1,1],[2,1],[3,1], [0,2],[1,2],[2,2],[3,2], [...

Re: Compiling polymake on macOS 10.14

I see, maybe I'll try cloning the release version from GitHub, I think I downloaded the perpetual beta.

edit: compiling the release version worked, thanks!

Re: Compiling polymake on macOS 10.14

Hi, I thought I'd post my question in the same thread, since I also have a problem building polymake on MacOS 10.14(.5) I get following error, which seems to be a problem with my compiler / C++ version. FAILED: /Users/yueren/polymake-beta/build/Opt/apps/common/cpperl/NodeHashMap.o g++ -c -o /Users/y...
