I'm trying to plot some 3d stuff from the cloud. I tried:

icosahedron()

and worked perfectly, but then I tried

v=[(0,0,0),(0,1,0),(0,2,1),(1,0,0),(1,2,3),(2,1,1)]
Polyhedron(vertices=v).plot()

and I only get a single bullet, no error message, no image, no nothing... What is going on?

I've fixed this particular bug in SageMathCloud 3d plotting -- it was caused by the plot method on polytopes bizarrely setting the width extra_kwds option, even though that is not used in Sage 3d plotting. Refresh your browser and it should work. (There's another polytope issue though.)

Indeed it works now, and is very fast, but still the results are not as good as with jmol. There I was using the thickness option to plot lines and edges and I get 3d objects that are thick cylinders, but here is not as pretty. Also I don't understand the shadows of the colors of the facets of the icosahedron. Anyway thanks a lot!

I don't know what is going on, but I do know that it is known and only a problem in the cloud.
