Well,the internet connection is terrible which makes me a mess... I downloaded the source(version 6.9 in Ubuntu 12.04).When I typed these following in sage command line,I got a problem...


It said something about jmol,so I went to get jmol,then invoked it again,however didn't work.IT SAYS: RuntimeError: jmol cannot run, no suitable java version found
And I tried to call jmol in Terminal,it seemed to work well.
Does sage cann't find the right path?What should I do?

Did you restart Sage after installing jmol?

This can also happen due to mismatched java version number. The java version expected by sage is declared in "~/.local/lib/python2.7/site-packages/sage/interfaces/" There, in the "JmolData" class at "is_jvm_available" function you'll find the code responsible for java version check.

java_version ="version.*[11][.][06]", version)

See, I've changed the version number to 11.06, it previously was 1.78(=[1][.][78]). Then voila, JMol started working normally.

This is what I get it to work.

  1. Run

/usr/libexec/java_home -V

  1. Identify version 8 of Java, and remove the others using a command like

rm -rf /Library/Java/JavaVirtualMachines/jdk-9.0.1.jdk/

(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.

I suggest visiting to check if your Java is up-to-date.

Another useful trick is to plot using threejs instead of the default Jmol.

For this, you could do:

sage: g = lambda x, y: x^2 + y
sage: plot3d(g, (1, 3), (1, 10), viewer='threejs')

... or use viewer='tachyon' when threejs also doesn't work (Windows 8, Sage 8.1).

@PHPirates -- was that with Firefox?

Viewing SageMath Three.js 3d plots in Firefox on Windows did not work in SageMath <= 8.9. But it worked in other browsers.

This problem was reported as

and fixed in

which was merged in Sage 9.0.beta9.

So, when Sage 9.0 comes out, viewing Three.js 3d plots in Firefox on Windows will work.

@slelievre I don't remember, and I don't have that Windows system anymore. However, I can say it works fine in Firefox under Linux, Sage 9.1.
