Sage can only plot the 1-skeleton right now, and it does this by using the graph theory component of Sage. So if you wanted to fill in the 2-cells, you would need to access the coordinates of the vertices in the plot of the graph and then plot the corresponding triangles. I think this is the way to proceed:

```
T = simplicial_complexes.Torus() # for example
G = T.graph()
P = G.plot(save_pos=True)
G.get_pos() # this will return the positions of the vertices
```

Unfortunately the vertices are forced to be in two dimensions, and I don't see an option like `save_pos`

for `G.plot3d()`

. So it may be hard to get meaningful shading on the triangles.

It's a good question, and we would welcome any contributions in this direction.

Another option (which would be more work but might be better in the long run) would be to implement a `save_pos`

option for `G.plot3d()`

and then use that for plotting the triangles.
