Saving 3d pictures as anaglyphs

I found this page which mentioned (near the bottom) that the Dodecahedral Graph can be rendered in 3D after which you could look at the anaglyph (3D red, cyan image). This picture image description

is shown (which appears to be Sage output) but I am unable to reproduce it. I tried

H=graphs.DodecahedralGraph().plot3d()
H.show(stereo='redcyan')
H.save("dodec.png")

but the resulting png image isn't in 3D. I tried adding stereo='redcyan', stereo =True, and other variations to the line saving the png but without success. How do I save anaglyphs like the image above?

Try getting the plot in the Jmol viewer without assigning it to a variable, so just

graphs.DodecahedralGraph().plot3d()

Once you have the Jmol viewer right-click the graph and choose 'Style -> Stereographic -> Red+Cyan'.

If you are not using the notebook (ie. running Jmol as an application), you can right click the graph again and choose 'File -> Export PNG Image'.

If you are using the notebook (ie. running Jmol as an applet), you can click the "Toggle Advanced Controls" buton and then the "Get Static Image to Save (Sleep)" button.

This should get you some version of the image you want.

Edit: Doing this in the notebook is slightly different, updated answer.

Thanks for your help. I struggled with the instructions, though, so for those with the same problem let me mention: I was working in the Sage Cell Server and still am unable to get the instructions to work. So I switched to the notebook, chose 'Style->Stereographic->Red+Cyan' and couldn't find any "Toggle Advanced Controls" button. There is, however, a "Get Image" button (I'm using Sage 4.8) below the image. Left clicking on that opened up a static version in my Chromium browser. Right clicking on the static image let me save it as a .jpg file. If you could explain more how to get a static picture from Sage Cell Server (I like to run the latest version) and/or where to find "Toggle Advanced Controls" button, that would be helpful.

If you are using the sage cell server, then getting the appropriate style can be achieved with 'Advanced -> Style -> Stereographic -> Red+Cyan'. I'm not really sure how to get the png file directly from the jmol viewer in this case (tried using the console but didn't make it work). But there is always the alternative of taking a snapshot of the screen (the way to get it will depend on the OS you are running :)
