3d graphics crash (on Mac)

[harald....@gmail.com]

Hi,

I am running Sagemath on a Mac Mini (2018; Intel).

I used to have no problems when asking Sagemath to display 3d objects (polygons), which I could then rotate, animate....

I haven't used my code for doing that sort of thing for a month or two or so. Yesterday, I loaded it again, and, to my surprise, the 3D-graphics capabilities of Sagemath kept crashing. (Firefox freezes for about a minute, and then things go on as normal, except there are no 3D graphics anymore - just a little circled "i" on the lower right corner.)

What may be going on? Upgrading from Sagemath 9.5 to 9.6 hasn't solved the problem.

Does it work with Safari or Chrome?

How does this look? http::///alan.atstafford.co.uk/Penrose/graphic.html

I am using Safari on MacBook Pro (13-inch, 2017, Two Thunderbolt 3 ports).

It looks just fine!

Chrome. Safari has some sort of problem when trying to load the page.

Chrome. Safari has some sort of problem when trying to load the page.

OK, if it works with Chrome, there isn't much we can do, after all, it's mostly 3rd party JavaScript which does this sort of graphics.

Anyway, if it stopped working by itself it means that a system (or browser) update happened in the meantime.

No, I meant that I get this sort of behavior (crash after starting to execute successfully) in Chrome. In Safari, the page doesn't even get started - it freezes after loading.

>Anyway, if it stopped working by itself it means that a system (or browser) update happened in the meantime.

What can I do about that?

I don't know how you installed Sage 9.6.

It might be that the macOS/browser updates came after the release date of 9.6, and thus all bets are off - in particular if it was a kind of binary distribution of Sage.

It was a binary distribution, but I installed it because I was having the same problem with sage 9.5 (compiled from scratch a few months ago).

Should I compile sage 9.6 from scratch?

it will work, most probably - although if the macOS/browser updates
appeared after 9.6, there could be a breakage.

I tried the following with the binary distribution of Sage 9.6, using  a jupyter notebook open in Firefox, on an Intel macbook air with Monterey:

from sage.plot.plot3d.shapes import *
S = Sphere(.5, color='yellow')
S += Cone(.5, .5, color='red').translate(0,0,.3)
S.show()

It worked fine.

(This is from the Sage 3D graphics documentation, but I left off the eyes and mouth.)

The sphere and cone worked fine in Safari too, after I changed my default browser.

[harald....@gmail.com]

That also worked fine for me.

[Marc Culler]

If you think this bug is specific to the binary package please feel free to report an issue at our github site:

https://github.com/3-manifolds/Sage_macOS/issues

Of course it would be helpful to have a short self-contained example of the failure ...
