D.13.3.23 texDrawNewtonSubdivision

Usage:

texDrawNewtonSubdivision(graph[,#]); graph list, # optional list

Assume:

graph is the output of tropicalCurve

Return:

string, the texdraw code of the Newton subdivision of the tropical plane curve encoded by graph

Note:

- the list # may contain optional arguments, of which only one will be considered, namely the first entry of type 'poly'; this entry should be a rational number which specifies the scaling factor to be used; if it is missing, the factor will be computed; the list # may as well be empty
- note that lattice points in the Newton subdivision which are black correspond to markings of the marked subdivision, while lattice points in grey are not marked

LIB "tropical.lib";
ring r=(0,t),(x,y),dp;
poly f=x+y+x2y+xy2+1/t*xy;
list graph=tropicalCurve(f);
// compute the texdraw code of the Newton subdivision of the tropical curve
texDrawNewtonSubdivision(graph);
