I'm using SageMath 8.1 on Windows 10 Native with Jupyter Notebook.

The only 3D viewer that works is tachyon.

Both threejs and jmol leave an empty space without plot but no error is issued, all this for the same 3D plot tachyon was able to plot.

FWIW this is basically a duplicate of https://ask.sagemath.org/question/406...

It is related: at that time I didn't know it is a general issue, I thought the problem was related to vector fields only.

A recent fix regarding Jmol with Windows has just been merged in Sage 8.2.rc1: #25021. Maybe this will solve your issue in Sage 8.2 (to be released soon).

Regarding the threejs issue, are you using the argument online=True along with viewer='threejs'? If yes, can you try with online=False?

I'm not using online=True

As per your suggestion I tried:

sage: sphere = surfaces.Sphere(center=(0, 1, -1), R=2); sphere
sage: sphere.plot(viewer='threejs', online=False)

It doesn't matter if I put online=False or online=True, I always get an empty space using threejs.

What about sphere.plot().show(viewer='threejs')?

@danielvolinski: given your answer, let me reverse my question: does it help to use online=True? (note: online=False is the default).

sage: sphere.plot().show(viewer='threejs') gives an empty space.

sage: sphere.plot(viewer='threejs', online=False) gives an empty space.

sage: sphere.plot(viewer='threejs', online=True) gives an empty space.

I created a ticket for this issue along with a fix: https://trac.sagemath.org/ticket/25129 It really should work with online=True unless of course you don't actually have an internet connection. Depending on the speed of your connection it might take a few seconds for the scripts to download--you can also try refreshing. Otherwise open your browser's developer console and see if there are any informative errors...
