Singular Manual: texDrawTriangulation

| #### D.13.6.23 texDrawTriangulation Procedure from library `tropical.lib` (see tropical_lib). Usage: texDrawTriangulation(triang,polygon); triang,polygon list Assume: polygon is a list of integer vectors describing the lattice points of a marked polygon; triang is a list of integer vectors describing a triangulation of the marked polygon in the sense that an integer vector of the form (i,j,k) describes the triangle formed by polygon[i], polygon[j] and polygon[k] Return: string, a texdraw code for the triangulation described by triang without the texdraw environment Example:
    LIB "tropical.lib";
    // the lattice polygon spanned by the points (0,0), (3,0) and (0,3)
    // with all integer points as markings
    list polygon=intvec(1,1),intvec(3,0),intvec(2,0),intvec(1,0),intvec(0,0),
    intvec(2,1),intvec(0,1),intvec(1,2),intvec(0,2),intvec(0,3);
    // define a triangulation by connecting the only interior point
    //        with the vertices
    list triang=intvec(1,2,5),intvec(1,5,10),intvec(1,2,10);
    // produce the texdraw output of the triangulation triang
    texDrawTriangulation(triang,polygon);
