Hi all,
I'm using <sageplot variant="3d"> for a 3D plot. The interactive HTML/three.js output looks great — text labels (text3d) included. But the static PNG used for the PDF/LaTeX version is noticeably worse overall, not just missing the text labels: the same Graphics3d object renders in a visibly lower-quality way for print than what I can get elsewhere.
A correctly-labeled, good-looking static image of the same plot is trivial to get outside this pipeline: e.g. a screenshot of the same Graphics3d object shown in a Jupyter notebook, where everything renders fine. So the "author supplies a static substitute" workflow is exactly the right one here — <sageplot> just has no attribute or child to receive it. (<interactive> already has this, via @preview or a <static> child — it's really just <sageplot> that's missing the equivalent.)
Is this a known limitation, and is there a workaround to get a good static image for print while keeping the interactive version for HTML? Or is something like @preview/<static> planned for <sageplot> too?
Thanks!
JC

Dear JC,
Our 3D plots from Sage have never been very good, and likely the code has not
been touched in years. So maybe we need to use better Sage code. Encouraging
authors to do extra work (manual screenshots) and override our automatic
production does not sound like the first solution to try.
Can we do something better (different Sage code) to get a better PNG (or other
format) image? Have you experimented within Sage itself?
I guess at worst, we might do the screenshots ourselves (i.e. automatically with
our existing tools)?

Dear Bob,
Yes, the problem comes from the fact that sage uses tachyon to save the 3d figures (I think). In any case, when i do my figure in a jupyter notebook and use Fig.save(...) I get the poor image pretext uses to build the pdf. Since the figures obtained as a preview for an "interactive" pointing to the sage one cell-server are quite good, I would say that this is the right mechanism. So is this a feature request? In the meanwhile, is there a workaround?

Hi JC,
You can use an interactive with @platform=“sage” containing a slate with @surface=“sage”. That will get you the automated screenshots. For example, Figure 11.8.9 in ACM is generated by xi:include of this file in this source file
I didn’t actually know that one could use a sageplot with code for a 3D image inside it, so this is how we’ve done all of ours.

HI Mitch,
Yes, I know I can do that. As I point ou, the figures obtained this way are fine, but in the .pdf version one gets those QR codes, this is why I prefer to avoir interactives. Is there a way to avoir the QR code? They are too big, I simply do not want them on the .pdf version of what I am writing.
Perhaps I am wrong, but I tend to think that relying on my local SAGE is kind of better. Any advice on this?

Hi JC,
For ACM, we use a mixture of just 3D plots and more elaborate Sage interacts, so standardizing has been mostly good for us. However, we do run into situations where the Javascript in the page of the book tends to be overloaded, so investigating if using sageplot for 3D may be something we look into. (There was also a day where the SageCellServer was down, which crippled our text.)
Disabling the QR codes could certainly be a feature request with possibly some design discussion around it. (For example, I imagine some texts will have sufficient margin space for the QR code to go into the margin, while others will have a page size that doesn’t leave much room for being in the margin. Some publishers may envision meaningful use of the PDF version in an electronic form, so the current triple of links might be useful for them. Other publishers want HTML to be the version used by readers on devices with PDF only for print, so just having the QR code will suffice. An option to configure the sidebyside that is produced for the static image and the QR code would be good as well.)
We are going to be shifting pretty seriously into thinking about the print version of ACM in the very near future, and getting good static versions (with minimal manual screenshotting) as well as a nice way for readers to access the interactive version will be a priority for us.

Thanks Mitch, for your insight.
So, at the end of the day, at this point, there is no way to obtain the nice figure one gets from sage one-cell server through an <interactive>, but directly from a <sageplot variant = "3d">. Am I right?
Does it make sense to ask for an improvement on the generation
of <sageplot variant = "3d"> either by parsing the sage code
to a one-cell server and then doing the screen shot in the usual
way, do all this locally, from sage, but avoiding sage itself to
save the figure?
In any case, at this point I am quite stuck with this. Any
suggestion?

Hello Bob,
Sage, called by pretext exports that poor .png figure. I did not modify
my sage code significantly, since the figure looks god in the applet, in
a jupyter notebook, in the one-cell server. What should I try if I try
to modify the sage code?
On the other hand, I had no answer about the two possibilities I mention.
Thanks,
JC

I think Rob’s suggestion was that PreTeXt should try to do better. I went looking into the XSL. When you have a sageplot, there is a call to the .save method of the graphics object. For 3D graphics, it looks like there are two options for the viewer: Jmol (default) and Tachyon. Would allowing authors to do some settings on a 3D sageplot to use the other viewer or adjust settings be a useful thing for PreTeXt to provide?

One issue is that Sage's current default for *viewing* is interactive, threejs (https://doc.sagemath.org/html/en/reference/plot3d/threejs.html), but the main way to get a *static* image is still Tachyon, which has the less nice pngs (but is very useful for creating larger animations). If you have a system where jmol is set up, it is (or was) also possible to save images by hand from there, but I don't know if there was a good automated way to do it.
As to threejs, if you do a search for "headless screenshot" or similar things (see e.g. https://threejs.org/manual/#tips#screenshot) there might be some interesting leads there as well for how to automate something for PTX, which would be quite valuable. I'm sure there are people on this list with expertise in things like puppeteer (or whatever the best current option is) who could whip something up.

Thanks, Mitch, for the translation/interpretation. That was exactly my intent.
JMOL! I'd forgotten about that. Some Java *molecule* viewer Sage used to
display 3D surfaces.
We are trying to fix LaTeX. We are not going to fix Sage as well. ;-)
#sageplot is great because you have a full spectrum of mathematical functions to
use. Asymptote and PreFigure are better choices for plots, I think. 3D exists
today for Asymptote and we can maybe cajole PreFigure to wander in that direction.
So we have whatever Sage gives us for 3D in static image formats. A first
suggestion would be to increase the resolution. I have not investigated the
missing labels yet.

Thanks very much, KDC. Good to have some Sage-knowledge weigh in, mine is
likely out-of-date. (And our messages have just crossed paths.)
We do headless screenshots already for #interactive, and similar. I am very
reluctant to "improve" Sage by going that route. My *opinion* is we take what
Sage gives us, for better or worse, in sickness and in health, and if we want
to, we can pester Sage to do a better job. I can't imagine we are the only
folks after better static images of 3D objects.
Or authors use Asymptote, and down the road, PreFigure.

3D exists today for Asymptote and we can maybe cajole PreFigure to wander in that direction.
Already wondering
