modules requiring java

[Ralf Stephan]

When giving for example a parametric_plot command to the Android app nothing happens and I found that apparently sagecell wants to start a Java applet on my browser. OTOH if I use Sage on my desktop a PNG is generated.

Is there a list of commands that will invoke some Java applet so that I can give app users a reason why things don't work?

Do you see a better solution? Is moving the computation to the client necessary? Are there HTML+Javascript alternatives planned for inclusion into Sage?

Regards,

Ralf Stephan

The *only* thing in all of Sage that will start a Java applet is the
default 3d plot renderer (jmol). Nothing else.
Maybe by parametric plot you mean parametric_plot3d?

Yes -- there's a lot of work on that. The three.js alternative for 3d
plotting is already the default in https://cloud.sagemath.com and can
be used via the threejs command in the Sage cell server
(https://sagecell.sagemath.org/).

Ah ok, so I accidentally hit the wrong button. Good to hear it's worked on.
