Re: [sage-support] Re: trouble displaying 3D graphics

[John Cremona]

As expected, using firefox to navigate to the file in .sage works fine.  
But also, I found that within a notebook the 3d display is just fine on 
chromium too -- complete with rotation and zooming in and out.  That is 
very nice.

Re: [sage-support] Re: trouble displaying 3D graphics

[John H Palmieri]

Is there a way for users to redefine SAGE_TMP (without editing Sage source 
code) so that these graphics files would be produced elsewhere?

Re: [sage-support] Re: trouble displaying 3D graphics

[John Cremona]

Thanks for all the replies. I did not respond earlier just because I have 
my Google groups set to daily summary for this group which meant that none 
of the replies even landed in my inbox until today's summary. That's not 
very helpful of Google.

OK, so for the time being I ll use Firefox to see these. I'm sure I will be 
able to find out how to get sage to use that instead of my default browser.

Right, one can see more of these "Chromium cannot open hidden
files/directories" posts
elsewhere, cf. e.g.
https://askubuntu.com/questions/1312932/cant-browse-access-hidden-files-and-folders-with-chromium

I don't see a good and quick way out, rather than renaming ~/.sage/ to
something without leading '.'.

I wonder if 'file:///' must be present in the URL for the script source for

it turns out it works in Firefox from terminal, too - I just needed to

fixed now, this way it works in Firefox as well as in Chrome.
Perhaps it has something to do with how the interaction of html/js works in
Sage.
Upon being posted to a proper http server, it works.
Without it, less so.

It works in Jupyter, i.e. if you start Sage as ./sage -n
and evaluate a cell with lines

var('x,y,z')
implicit_plot3d(x^2+y^2+z^2==4, (x,-3,3), (y,-3,3), (z,-3,3))

you get the picture all right.
