You're hitting a bug in sage-6.3 (the bug has nothing to do with SageMathCloud). It's evidently fixed in sage-6.4, but even then, I don't think that way of viewing a tachyon plot would work in SMC. In any case, here's how to do this in SMC, which works now:
f = lambda t: (t,t^2,t^3)
t = Tachyon(camera_center=(5,0,4))
t.texture('t')
t.light((-20,-20,40), 0.2, (1,1,1))
t.parametric_plot(f,-5,5,'t',min_depth=6)
t.save('a.png')
salvus.file('a.png')
Here's a worksheet illustrating make the 3d plot you want to make, using the regular interactive 3d viewer and also tachyon:
