Draw a tiled cube of any size

Question

Draw a tiled cube of any size, in ASCII art.

You will be given three numbers a, b and c, and the program should output an a*b*c sized cube.

Examples

3 3 3 ->

Shortest code wins.

Answer 1

Python, 145 chars

a,b,c=map(int,raw_input().split())
for i in range(b+c+1):print(' '*(c-i)+((' /|'[(i>c)+(i>0)]+'_'*4)*(a+1))[:-4]+('|'*(b+c-i))[:b]+'/')[:5*a+c+1]

$ echo "5 6 3" | ./cube.py

Answer 2

Mathematica 148 143 139 chars

I decided to use transparent glass tiles.

The following code prints ASCII characters "-" in the form of a cuboid with edges, a, b, and c. The only thing you see in the figure below are hyphens.

w_~e~_ := {Arrowheads@Table[{1, p/9, Graphics@Style[Text["-"], Red]}, {p, 9}], White,Arrow@w};
GridGraph[{a, b, c} + 1, VertexSize -> 0, EdgeShapeFunction -> e]

Answer 3

C, 226, 212

s(x,y){x<1?:putchar(" |/_\n"[y],s(x-1,y));}i,j,x,y,z;main(){for(scanf("%d%d%d",&x,&y,&z);j<=y+z;s(i,1),s(j++>y,2),s(1,4)){s(z-j,0);for(i=x;s(1,j?j>z?1:2:0),i;i--)s(4,3);i=y+z-j;if(i>j)i=j;if(i>z)i=z;if(i>y)i=y;}}

Once again a poor score compared to other langs - so any C golf gurus able to improve?

Answer 4

Python3 (188)

a,b,c=map(int,input().split())
x=a+1
k="_"*4
p=print
l=5*a+c+1
p(" "*c+k.join(" "*x))
r=" "*c+k.join("/"*x)+"|"*b+"/"
exec("r=r[1:];p(r[:l]);"*c+'b-=1;p((k.join("|"*x)+"|"*b+"/")[:l]);'*b)

It is beaten already, but idea could help someone-else.
