Visualizing of subdivision

[saschatimme]

If I want to visualize a polyhedral subdivision I get a rather cryptic error.

julia> using Polymake

julia> A = [2 1 0; 0 0 2]'
3×2 LinearAlgebra.Adjoint{Int64,Array{Int64,2}}:
 2  0
 1  0
 0  2

julia> lift = Rational{Int64}[5//1, 3//1, 5//1]
3-element Array{Rational{Int64},1}:
 5//1
 3//1
 5//1

julia> subdiv = @pm Fan.SubdivisionOfPoints(POINTS=A, WEIGHTS=lift)
type: SubdivisionOfPoints<Rational>

POINTS
1 0
1 0
0 1


WEIGHTS
5 3 5


julia> Fan.visual(subdiv)

Visualizing our favourite 3-cube on the other hand works perfectly.

please homogenize your input:

julia> A = [1 1 1; 2 1 0; 0 0 2]'
3×3 LinearAlgebra.Adjoint{Int64,Array{Int64,2}}:
 1  2  0
 1  1  0
 1  0  2

julia> lift = Rational{Int64}[5//1, 3//1, 5//1]
3-element Array{Rational{Int64},1}:
 5//1
 3//1
 5//1

julia> subdiv = @pm Fan.SubdivisionOfPoints(POINTS=A, WEIGHTS=lift)
type: SubdivisionOfPoints<Rational>

POINTS
1 2 0
1 1 0
1 0 2

julia> Fan.visual(subdiv)

edit: There might still be something wrong because I think technically your input is valid ...
