20180228 21:39:40 +0200  answered a question  jmol cannot run while plot3d This is what I get it to work.
(with the version suitably changed; also you'll probably have to run this as sudo) It turns out that JMol is incompatible with version 9, which I originally had. After getting rid of version 9, closing the shell session and restarting it, I am now able to plot 3d objects in Sagemath through JMol.

20171115 22:09:44 +0200  commented answer  Visualizing Toric fans in Sage Thank you, Dan! Sorry for my late reply. This is indeed helpful. I meant "dual toric diagram" not "dual fan" (thanks for correcting me). What if I had to go backward (dual of dual toric diagram)? Would this method still work? If you see https://arxiv.org/pdf/0706.1310.pdf, essentially what I want to do is generate either one of Figure 2.3 given the other.

20171109 21:42:47 +0200  asked a question  Visualizing Toric fans in Sage I am learning basics of toric geometry as applied to physics. I would like to know if there's a way to visualize toric fans using Sagemath, and also draw dual toric diagrams. For example, if I give explicit coordinates of vectors defining a fan, can I visualize the fan and also its dual toric fan using Sage? I have found resources on the net about using Sage for toric varieties, but I am currently looking for answers to much simpler questions. 
20171108 00:17:01 +0200  commented answer  Sage on Mac unable to use plot3d due to Java/jmol issues Thanks, Dan. I don't seem to have canvas3d; the graphics quality using tachyon is very poor for some reason: the figure appears dithered.

20171108 00:13:40 +0200  commented answer  Sage on Mac unable to use plot3d due to Java/jmol issues Thanks eric_g! This worked. But it launches a browser (Safari, in my case). Is there a way to get it to work like jmol would (i.e. without a browser)? 
20171107 17:39:01 +0200  asked a question  Sage on Mac unable to use plot3d due to Java/jmol issues Hi, I am a relative newbie to the Mac and Sage on the Mac. I tried to run the following code from the Sage tutorial on my Mac in the console mode of sage:
The error message I get is
I believe I have the latest version of Java installed:
Sage version
I would appreciate any inputs and advice about how to fix this issue. Thanks in advance!
