plot3d showing a blank page (WSL)

[G. M.-S.]

A very short question (hoping it is not a stupid one).

How to make

online=True

the default for plot3d and related commands?

Background:

• SageMath on Windows through WSL (using Conda or an AppImage).
• Windows browser (because Ubuntu browser seems to be too slow).
• plot3d gives a blank page.

This seems due to the temporary HTML file created by plot3d containing

<script src="/var/tmp/sage-10.7/local/share/threejs-sage/r122/three.min.js"></script>

which is not accessible from the Windows browser (even after changing the path).

Possible workarounds are:

1. Copy three.min.js to the temporary directory of the HTML file and modify the line above:
   <script src="three.min.js"></script>
   but this file is 656 KB, so multiple invocations of plot3d will take a lot of space.
2. Copy three.min.js to a directory accessible from the Windows browser.  I do not know if this is possible.
3. Use plot3d( … , online=True) which changes the line above to
   <script src="https://cdn.jsdelivr.net/gh/sagemath/threejs-sage@r122/build/three.min.js"></script>
   but this needs internet access.

TIA for your help.

Hi Guillermo,

The AppImage creates a symlink (in the WSL linux filesystem) pointing from /var/tmp/sage-10.7 to the root of the AppImage's fuse mounted filesystem, which contains Sage's local directory.

A Google AI search claimed (probably incorrectly) that the following would work if you are using the default Ubuntu image in WSL:

<script src="file:////wsl.localhost/Ubuntu/var/tmp/sage-10.7/local/share/threejs-sage/r122/three.min.js"></script>

You could try that.
