I am looking for guidance on how to recreate the attached image (image.png) entirely within LaTeX using TikZ. The image consists of two main complex elements: A red ribbon with intricate curves and realistic 3D-like gradient shading. A multi-faceted jewel/diamond in the center with sharp light reflections. Initially, I thought simulating this 3D effect in TikZ would be too complex, but following the community's helpful feedback and advice on providing a Minimal Working Example (MWE), I decided to tackle both the ribbon and the central jewel to demonstrate my progress. I managed to draw the ribbons using manual Bézier curves and custom shadings to simulate the folds. For the jewel, I used a clipping mask and layered semi-transparent polygons (opacity) to mimic the glass facets and light reflections. Here is my current MWE: \documentclass[tikz,border=5mm]{standalone} \usetikzlibrary{shadings,calc} \definecolor{ribbonred}{RGB}{215,10,28} \begin{document} \begin{tikzpicture}[x=3cm,y=3cm] \begin{scope} \fill[% top color=ribbonred!20!black, bottom color=ribbonred!20!black, middle color=ribbonred, shading angle=150] (-0.463,-0.006) .. controls (-0.497,-0.017) and (-0.649,-0.048) ..

Additionally, I really struggled with color coordination and picking the right shades for the gradients. If anyone could help me adjust the color palette to make the ribbon look more naturally glossy and realistic, I would be very grateful. I also want to thank kabenyuk for their excellent answer which showed how to modularize the ribbon drawing! Any further improvements or tips on combining these elements effectively would be greatly appreciated.

When I work on TexStudio and I put my Mac to sleep, 8 times out of 10, when I reopen my laptop, I get the following message (see image). I have seen some similar post but either the problem is slightly different (only happens to me when I close the laptop, and files are not corrupt) or the suggested solutions do not work (I don't see the file mentionned in one similar discussion). What could I do?

I am using reledpar to match up occasional lines of prose on my righthand (odd) pages with continuous verse on the lefthand (even) pages, treating each verse line and each prose entry as its own chunk to ensure they line up. I am using reledmac's \stanza command on the left; on the right it doesn't seem to make a difference which type of numbered text I use, but semantically \pstart and \pend better describe the content type than \stanza. Where I have no prose content, I enter an empty chunk (i.e. \pstart\pend, or & if using \stanza on righthand pages). Where right-hand prose content extends across more than one printed line, the sync process (in the second compilation run) inserts empty lines between the verse lines on the left. This is as designed, but not desired in my case. I am wondering if there is a way to forbid the sync process from creating empty lines on lefthand pages, postponing the next righthand chunk by the number of line breaks within the content of an immediately preceding chunk (or, better: unbroken sequence of non-empty chunks) of content. returning to exact syncing as soon as the presence of empty chunks in the righthand content equals the number of surplus line breaks within preceding chunks on the same page. Bonus: I also don't mind if prose chunks are merged in the process; I don't need a new prose entry to start on a new line, I just want it to occur as close as possible vertically to the matching verse. In other words, I would rather have righthand content show up one or two lines late from time to time than seeing blank lines on the left, but it would be ideal if such a mismatch could then be resolved as soon as space allows. It doesn't seem to me the answer involves either of the shiftedpstarts options, as I need line-by-line syncing; accordingly, this answer doesn't seem to solve my issue.

I'm using MacTeX 2022 on an antique Mojave 10.14.6 system. I employ XeLaTeX with a commercial font and document formatting via the memoir class. I've searched a bit into the minted and listings packages but they don't seem to do what I'd like. What I'd like to do is be able to select ranges of lines (e.g., lines 2-5, 6-9, etc.) and have the input be formatted (i.e., font/size, etc.) by what's in the preamble of the importing document. Minted seems to make what's imported a verbatim format, whereas I'd like any and all the text and markups processed, not printed. I haven't been able to get listings to do anything yet.

I want to get a oneside document, whose everypage holds left margin region as below: The target sketch above was the second page given by: \documentclass{book} \usepackage[ showframe, includemp, textwidth=12cm, marginparsep=0.5cm, marginparwidth=5cm, ]{geometry} \usepackage{amsmath} \usepackage{lipsum} \begin{document} \section{Test Test Test Test} \lipsum[1-3] \lipsum[1][1]\marginpar{\raggedright\lipsum[2][1-4]}\lipsum[2-3] \section{Test Test Test Test} \lipsum[1-3] \lipsum[1][1]\marginpar{\raggedright\lipsum[2][1-4]}\lipsum[2-3] \end{document} Now, I want to fix the geometry paramters, change to oneside, and add \reversemarginpar: \documentclass[oneside]{book} \usepackage[ showframe, includemp, textwidth=12cm, marginparsep=0.5cm, marginparwidth=5cm, ]{geometry} \usepackage{amsmath} \usepackage{libertinus-otf} \usepackage{lipsum} \reversemarginpar \begin{document} \section{Test Test Test Test} \lipsum[1-3] \lipsum[1][1]\marginpar{\raggedright\lipsum[2][1-4]}\lipsum[2-3] \section{Test Test Test Test} \lipsum[1-3] \lipsum[1][1]\marginpar{\raggedright\lipsum[2][1-4]}\lipsum[2-3] \end{document} The result was unexpected: My question is that, in my ideal "left margin region" oneside document, the settings: \usepackage[ showframe, includemp, textwidth=12cm, marginparsep=0.5cm, marginparwidth=5cm, ]{geometry} was enough to reverse the margin, I don't want to manually calculate something like left=? within geometry setting. I wonder how to get a "oneside" document with reversed "left margin region" everypage without specifying/calculating parameters other than textwidth=12cm,marginparsep=0.5cm,marginparwidth=5cm.

How can you obtain automatically all the available fonts in "https://ctan.org/pkg/lua-unicode-math" ( https://ctan.org/pkg/lua-unicode-math )

(This is a follow up of the answer to the question of mine: How to get a dedicated geometry only for the two pages following the page dedicated to the chapter title?) In the following MCE, the space above the section title is ignored at pagebreak and hence the texts on the two facing pages start at the same height: so far, so good. \documentclass{article} \usepackage[paperwidth=120mm,paperheight=120mm]{geometry} \usepackage[color=red,showframe,type=alledges]{fgruler} \usepackage{afterpage} \usepackage{lipsum} \newlength\myskip \setlength\myskip{1cm} \begin{document} % \vspace*{\myskip}\afterpage{\vspace*{\myskip}} % Foo bar. \section{Baz} \lipsum[1-2] \end{document} If we uncomment the two commented lines, the result is as expected: the texts on the two facing pages start at the same height, with a common vertical blank space at the top of the pages: But, if only \vspace*{\myskip}\afterpage{\vspace*{\myskip}} is uncommented (that is if the texts on the two facing pages are supposed to start with a common vertical blank space at the top of the pages, but the one on the left page starts with a section), there is an extra vertical space above the section title which induces a vertical shift between the texts on the two facing pages: How to get rid of this vertical shift in the latter case?

I made the following diagram, which is supposed to depict how the intersection of two intervals can be determined. However, as you can see, I could include only one number line, which makes the diagram look rather empty, in my opinion. Is there a away to draw two more number lines above the original one, aligned with the "flying" blue intervals? I have thought about drawing three separate tikz pictures above each other, but then I can't draw the red dashed line, and it would also make it difficult to control the invisible space taken by the y-axis. \documentclass{book} \usepackage{pgfplots} \begin{document} \begin{tikzpicture}[every node/.style={font=\small},] \begin{axis}[ clip=false, axis x line=middle, axis y line=none, x axis line style={<->}, xmin=-3.4, xmax=7.4, ymin=-.5, ymax=3, xtick distance=1, x=.6cm, y=1cm, ] % Red dashed lines \draw [red,dashed] (axis cs:-1,0) -- (axis cs:-1,2.2) (axis cs:6,0) -- (axis cs:6,2.2); % Points \addplot[only marks,mark options={fill=white}] coordinates {(6,2) (-1,1) (6,0) (-1,0)}; % Uppermost number line for x < 6 \draw[<-,very thick] (axis cs:-3,2) -- (axis cs:6,2); % Middle number line for x > -1 \draw[->,very thick] (axis cs:-1,1) -- (axis cs:7,1); % Lower number line for intersection of inequalities \draw[very thick] (axis cs:-1,0) -- (axis cs:6,0); % Labels \draw (axis cs:8,2) node[right]{$x<6$} (axis cs:8,1) node[right]{$x>-1$} (axis cs:8,0) node[right]{$x<6$ and $x>-1$, or simply $-1<x<6$.}; \end{axis} \end{tikzpicture} \end{document} Here is what it looks like (note I have removed color and font information from the code to keep things simple).

If I use \autocite[3:1–651]{OwenWorks}, I get: Owen, Works, 3:1–651. This does not include the title of the work Pneumatologia.

The LaTeX format has recently implemented templates for block environments, lists, and headings. Is there a collection of examples of using these templates for document design? (I'm only aware of the examples for ltx-talk.) It's not easy to search for "examples of LaTeX templates" online -- the wrong stuff comes up! Addendum: the ltx-talk examples are here.

Thank you.

How can I format the derivative of a long vector function in LaTeX so it does not spill over the page margin?

Does plain TikZ have a built-in way to reuse intermediate mathematical calculations across plot dimensions? I mean I could just use a foreach loop and pgfmathsetmacro, but that's quite intensive. Is this built in to plot? If not, should/could it be? I mean, I doubt it, but I also doubted that my previous question had a good solution - which I, to my pleasant surprise, turned out to be wrong about. % Source - https://tex.stackexchange.com/a/764941 % Posted by kabenyuk, modified (!) by Jasper.

Is Latex capable of producing a gold pattern similar, for example, to the (thick) gold border on the outside of this cover: It does not seem that either pgfornament or psvectorian are what is needed here. Is there some other package that I might use that is up to this job? If not, what resource might I use to produce a similar border? I expect to compile with xelatex.

How to obtain (a list) all the fonts installed in the TeX installation and in the system. Similar to https://tug.org/FontCatalogue/alphfonts.html but better in PDF pages.

I would like to break between pages an align* environment, yet it does not work. I use \tcbsetforeverylayer[breakable] so that all nested tcolorbox environment that I use can break between pages and \allowdisplaybreaks for breaking align* environment in pages. When I try to put an align* environment in my theorem (or leftrule) environment, it breaks between pages.

I'm trying to redefine \chapterformat with the koma scrbook class to have ordinal chapter numbers (1er, 2e, 3e in french) in the first chapter page (not in the ToC or elsewhere).

I am working on a document where I created a custom page border and headers/footers using TikZ and eso-pic. However, the document is extremely heavy to process. The compilation time is very slow, and it gets significantly worse as the number of pages increases. Is there a more efficient way to write this code? For example, is there a way to render the background only once and reuse it across all pages (like saving it to a box), instead of drawing these complex paths and loops on every single page?

Also, I am using some local Arabic fonts in my code (Aljazeera.ttf and Al Qalam Quran Majeed Web.ttf). If you want to test the code on your machine, you can simply comment them out or replace them with any standard font (like Amiri). My main problem is that compiling this document is extremely slow because of the complex TikZ background (especially the loops and smooth paths). The processing time gets heavier and heavier with every new page added. Is there a way to optimize this? For example, is it possible to render this background only once (saving it into a box) and reuse it on every page to drastically reduce the compilation time? Any help or optimized code would be highly appreciated. Thank you! EDIT/UPDATE: I sincerely apologize for my previous code. I realized it contained local Arabic fonts and packages (polyglossia) which made it impossible for you to compile and test. I have completely cleaned up the code. It is now a proper Minimal Working Example (MWE) using only standard packages and example-image. My issue is that this document is extremely slow to compile because of the complex TikZ background (the loops, \whiledo, and smooth curves). The compilation time increases heavily with every new page. As pointed out in the comments, I need to separate the static parts (the complex borders/decorations) from the variable parts (like the page number), but my code is too entangled with nested tikzpictures and tcolorbox. Could someone please provide a structural example of how to redesign this so the heavy background is drawn/saved only once, drastically reducing compilation time? Here is the clean, compilable MWE (you can test it with pdfLaTeX): \documentclass[a4paper]{report} \usepackage[right=1.1cm,left=1.3cm,top=2.5cm,bottom=2cm,foot=0mm,head=0mm]{geometry} \usepackage{amsmath,amsfonts,eso-pic,amssymb,mathrsfs,tikz,fancyhdr,multicol,pifont,ifthen,lastpage,graphicx} \usepackage[most]{tcolorbox} \usetikzlibrary{arrows,shapes,calc} \parindent=0mm \colorlet{col1}{blue} \colorlet{col2}{col1!50} \pagestyle{empty} \newcounter{tabb} \newcommand{\shape}[2][1]{\setcounter{tabb}{1}\tabcolsep=0mm\begin{tabular}{c} \whiledo{\thetabb<#2}{\hskip-3pt% \tikz{\path[top color=col2,bottom color=col2,middle color=white] (3.9cm,-.7)rectangle(7.1cm,7mm); \draw[.!50!col1] (3.9,-.7)--(7.1,-.7)(3.9,.7)--(7.1,.7); \draw[line width=3pt,smooth,inner color=white,outer color=gray,draw=.!25!gray] plot[domain=3.9:7.1] (\x,{sin deg(\x)}) plot[domain=3.9:7.1] (\x,{cos deg(\x)}); \draw[transform canvas={yscale=#1},line width=3pt,smooth,inner color=white,outer color=gray,draw=.!25!gray] plot[domain=3.9:7.1] (\x,{sin deg(\x)}) plot[domain=3.9:7.1] (\x,{cos deg(\x)});}\stepcounter{tabb}}% \end{tabular}} \AddToShipoutPicture{ \begin{tikzpicture}[overlay,remember picture] \coordinate (1) at ([shift={(-.8,-1.25)}]current page.north east); \coordinate (2) at ([shift={(.8,-1.25)}]current page.north west); \coordinate (3) at ([shift={(.8,1.25)}]current page.south west); \coordinate (4) at ([shift={(-.8,1.25)}]current page.south east); \path (2)--node[scale=0.2,rotate=90,inner sep=0mm]{\shape{41}}(3); \path (1)--node[scale=0.2,rotate=90,inner sep=0mm]{\shape{41}}(4); \coordinate (5)at ($(1)!1/4!(2)$); \coordinate (6)at ($(1)!3/4!(2)$); \coordinate (7)at ($(4)!1/4!(3)$); \coordinate (8)at ($(4)!3/4!(3)$); \path (1)--node[scale=0.2,inner sep=0mm]{\shape{4}}(5); \path (2)--node[scale=0.2,inner sep=0mm]{\shape{4}}(6); \path (4)--node[scale=0.2,inner sep=0mm]{\shape{4}}(7); \path (3)--node[scale=0.2,inner sep=0mm]{\shape{4}}(8); \foreach \i/\j/\k in {1/1/1,2/-1/1,3/-1/-1,4/1/-1}{ \node [inner sep=0mm,left] at (\i) {\scalebox{\j}[\k]{% \tikz[transform canvas={shift={(-.5mm,-.4mm)}}]{ \coordinate (a)at (0,0); \draw[inner color=white,outer color=gray]([shift={(-2mm,1mm)}]a)to[out=250,in=-45]([xshift=-1.6cm,yshift=-.8mm]a)-|+(.14,2mm)to[out=-45,in=240]([yshift=-3mm,xshift=-2mm]a); \draw[inner color=white,outer color=gray] ([yshift=-.75cm,xshift=1.5mm]a)to[out=40,in=-90]([xshift=-1mm,yshift=2mm]a)--([xshift=-3mm,yshift=2mm]a)to[out=-90,in=10]([shift={(-1mm,-.75cm)}]a); }% }}; \node[inner sep=0mm,scale=2,text=col1] at (\i){% \includegraphics[width=.5cm,height=.5cm]{im1}% }; } \node[text width=0.75\textwidth,inner sep=0mm,baseline={(1.east)}] at ($(1)!.5!(2)$){ %\begin{otherlanguage}{arabic} \begin{tcolorbox}[enhanced,nobeforeafter,right=5mm,left=5mm,frame empty,fontupper=\bfseries\large,interior code={ \path[draw=col1,line width=.8pt,bottom color=col1!50,top color=col1!50,middle color=white] ([yshift=1.5mm]interior.east)to[out=180,in=0]([xshift=-2cm]interior.north east)--([xshift=2cm]interior.north west)to[out=180, in=0]([yshift=1.5mm]interior.west)to[bend left]([yshift=-1.5mm]interior.west)to[out=0,in=180]([xshift=2cm]interior.south west)--([xshift=-2cm]interior.south east)to[out=0,in=180]([yshift=-1.5mm]interior.east)to[bend left]cycle; \path(interior.east)-- node[pos=0.33,yscale=.8,xscale=.5,inner sep=0mm]{\colorlet{gray}{col1}\shape[-1]{2}} node[pos=0.69,yscale=.8,xscale=.5,inner sep=0mm]{\colorlet{gray}{col1}\shape[-1]{2}}(interior.west); }] text left \hfill text center \hfill text right \end{tcolorbox}% %\end{otherlanguage}% \vglue-\baselineskip }; \node[text width=0.75\textwidth,inner sep=0mm] at ($(4)!.5!(3)$){ \begin{tcolorbox}[enhanced,nobeforeafter,right=5mm,left=5mm,frame empty,top=0mm,bottom=0mm,fontupper=\bfseries\large,interior code={ \path[draw=col1,line width=.8pt,bottom color=col1!50,top color=col1!50,middle color=white] ([yshift=1.5mm]interior.east)to[out=180,in=0]([xshift=-2cm]interior.north east)--([xshift=2cm]interior.north west)to[out=180, in=0]([yshift=1.5mm]interior.west)to[bend left]([yshift=-1.5mm]interior.west)to[out=0,in=180]([xshift=2cm]interior.south west)--([xshift=-2cm]interior.south east)to[out=0,in=180]([yshift=-1.5mm]interior.east)to[bend left]cycle; }]\centering Page 1 of 1 \end{tcolorbox}% %\end{otherlanguage}% \vglue-\baselineskip }; \end{tikzpicture} } \begin{document} hey \end{document}

I am typesetting a Dutch text in lualatex / polyglossia. All hyphenation instances occur correctly, but one: Nederlands-Indië, which I coded as Nederlands\hyp{}In\-dië, in order to preserve the dash and to encourage hyphenation between n-d. Correct hyphenations are: Neder- lands-Indië Ne- derlands-Indië Nederlands- Indië Nederlands-In- dië. Note that in all these cases the dash remains. However, in my text it is occasionally also hyphenated as: Nederlands-Indi- e. This is incorrect and ugly typesetting, because of the single e on the new line. It is probably caused by the fact words containing an ë (e-trema) are hyphenated, e.g. in the case of geënt, ë indicates a new syllable. Therefore ge- ent is correct. I tried settings like these, \lefthyphenmin=3 \righthyphenmin=3 \hyphenpenalty=500 but the problem persists. Has anyone a solution?

I have been trying to make my course book more accessible by tagging it with tagpdf as I formulated in the title. I use TexStudio and have tried compiling with PDFLaTeX and LuaLatex (before I used XeLaTeX because of specific font preferences but that's another subject, I am adding it just in case). I added \DocumentMetadata{lang=fr,tagging=on,pdfstandard=UA-2} before \documentclass{book}. The error I get when compiling is: The key 'document/metadata/tagging' is unknown and is being (LaTeX) ignored. ...Metadata{lang=fr,tagging=on,pdfstandard=UA-2} I tried to install the 2026 TexLive version since the one from my Debian distribution (Debian12, upgrading to 13 failed, I am on a 2017 MacbookAir with Debian) seems to date from 2022. I am not a true geek and have not been able to find an accessible solution to my question which is fundamentally, how to best tag my course book if my solution to use TexLive 2026 is correct and the 2022 version may be the origin of the problem of not recognising \DocumentMetadata, how to point TexStudio to the installed 2026 TexLive version or how to compile the file using LuaLaTeX from the 2026 TexLive install? Thanks already!! UPDATE Thanks to @cfr and @ samcarter_is_at_topanswers.xyz : On solution to make \DocumentMetadata (and thus tagging) work is, when the latest TeXLive version is installed, to point TexStudio to it : indicate the directory where TexLive 2026 is located, e.g. in my case on Debian 12 /usr/local/texlive/2026/bin/x86_64-linux/lualatex %, in the "default compiler" field of the texstudio advanced configuration "Build" tab (note the % at the end, which gets replaced by the file name by texstudio). (I chose to keep the default 2022 apt installation/packages of TexLive on Debian in addition to the 2026 installation because of my moderate literacy).

I'd like to have a bibliography per chapter using biblatex, along with a final, global bibliography at the end. Here's what I have for now. \documentclass[a4paper, 11pt]{book} \usepackage[english]{babel} \usepackage[% sorting=nty,% style=alphabetic,% backref=true,% refsegment=chapter,% isbn=false,% ]{biblatex} \usepackage{csquotes} % Recommended by biblatex \addbibresource{main.bib} % Hyperlinks \usepackage[linktocpage=true]{hyperref} \begin{document} \chapter{First chapter} Let's cite \cite{AN25} here. \printbibliography[segment=\therefsegment,heading=subbibliography] \selectlanguage{english} \chapter{Second chapter} Let's also cite \cite{AN25} here. \printbibliography[segment=\therefsegment,heading=subbibliography] \appendix \printbibliography \end{document} with main.bib containing @misc{AN25, author={Doe, John}, title={What a title}, year=2025, } There are however two problems with this code, that I think may be related. First of all, the first bibliography contains backreferences to the second chapter. This is not dramatic, though if possible I'd rather not having this, but more importantly may be linked to the second problem, which is that the hyperlink [Doe25] in the second chapter sends to the first bibliography. Is there a way for the hyperlink to send the reader to the current chapter's bibliography? Note that I've also tried to add the method described in this post by adding backend=biber adding natbib=true removing the segment=\therefsegment adding the relevant piece of LaTeX3 code which resulted in the following code: \documentclass[a4paper, 11pt]{book} \usepackage[english]{babel} \usepackage[% sorting=nty,% style=alphabetic,% backref=true,% refsegment=chapter,% isbn=false,% backend=biber, natbib=true, ]{biblatex} \usepackage{csquotes} % Recommended by biblatex \addbibresource{main.bib} \usepackage{xparse} \ExplSyntaxOn \seq_new:N\g_UF_allcitekeys_seq \AtEveryBibitem { \seq_gput_right:Nx\g_UF_allcitekeys_seq{ \thefield{entrykey} } } \NewDocumentCommand\nociteall { } { \seq_map_function:NN\g_UF_allcitekeys_seq\nocite } \ExplSyntaxOff \makeatletter %for the backrefs of the main bib: \let\oriabx@aux@backref\abx@aux@backref \renewcommand\abx@aux@backref[5]{% \oriabx@aux@backref{#1}{#2}{#3}{#4}{#5}% \oriabx@aux@backref{#1}{#2}{0}{#4}{#5} } \makeatother % Hyperlinks \usepackage[linktocpage=true]{hyperref} \begin{document} \chapter{First chapter} Let's cite \cite{AN25} here. \printbibliography[segment=\therefsegment,heading=subbibliography] \selectlanguage{english} \chapter{Second chapter} Let's also cite \cite{AN25} here. \printbibliography[segment=\therefsegment,heading=subbibliography] \appendix \printbibliography \end{document} but both issues persist. Am I missing something obvious?

I wonder how an entire picture created with tikzpicture can be positioned in a Beamer slide, that is, my purpose is to positioning all tikzpicture in the slide with custom precision (e.g., by using coordinates). I tried \hspace and \vspace but the results are not good. Find my code below: \documentclass{beamer} \usepackage{tikz} \usetikzlibrary{tikzmark,calc,positioning,fit,arrows,shapes,backgrounds,shapes.geometric,arrows.meta,patterns.meta,decorations.pathreplacing} \begin{document} \begin{frame} \begin{tikzpicture} \fill[blue] (0,0) circle (0.5); \fill[red] (1,0) circle (0.5); \end{tikzpicture} \end{frame} \end{document} (compiled via Lua LaTeX). With thanks

How can I handle division by zero and non-Euclidean distortions in Asymptote without erroring? My goal is to illustrate point-at-infinity illustrations. For example, try setting MAIN_PARAMETER to 180, which is a full inversion, and I cannot achieve it due to the error. Moreover, the diagram seems to not handle the distortions well leading up to these errors. import three; import graph3; real MAIN_PARAMETER = 20; unitsize(1cm); currentprojection=orthographic(1,2,3); triple SP(triple point){ return ( point.x / (1 - point.z), point.y / (1 - point.z), 0 ); } triple ISP(triple point){ real temp = point.x^2 + point.y^2; return ( 2 * point.x / (1 + temp), 2 * point.y / (1 + temp), (-1 + temp) / (1 + temp) ); } transform3 R = rotate(MAIN_PARAMETER, (1,1,0)); triple riemann(pair uv){ return R*ISP((uv.x,uv.y,0)); } triple mobius(pair uv){ return SP(riemann(uv)); } surface theriemann = surface(riemann, (-2, -2), (2, 2), Spline); draw(theriemann, green, meshpen=black + 0.5pt); surface themobius = surface(mobius, (-2, -2), (2, 2), Spline); draw(themobius, blue, meshpen=black + 0.5pt); Without much distortion, it is fine: With a lot of distortion, it is not:

Why lorem/lipsum use makes that spanish decimmal is not comma, as expected?. \documentclass[12pt,a4paper]{article} \usepackage[spanish,es-notilde,]{babel} %\spanishdecimal{,} \usepackage{amsmath,mathtools} \usepackage{amssymb} \usepackage{siunitx} \sisetup{output-decimal-marker={,}} \usepackage{lipsum} \begin{document} \lipsum[1] \textbf{If you comment the previous \texttt{lipsum[1]} you obtain comma as decimal separator in the next 2 lines, as expected in spanish.} Decimal: $\dfrac{7}{4}\approx 1.75$ $\angle{3.4;2}$ No problem in the next lines: $\ang{3.4;2}$ $\num{5.5}$ \end{document}

I was making a rational double pendulum in Asymptote: // a rational double pendulum import graph; unitsize(3cm); pair truncated_pi(real t) { real t1 = 3.14 * t; return ( cos(t) + cos(t1), sin(t) + sin(t1) ); } path f = graph(truncated_pi, 0, 314, n=10000); draw(f); I wanted to make it in TikZ, but I am running into the issue of needing a number of samples which is beyond the limit imposed by pgfmath. As some of you may be familiar with, I am very fond of plain TikZ. I would like to see if there are ways to achieve this which are not overly ad hoc. For example, one strategy would be to break the domain into separate regions. How would one draw something like this in the spirit of plain TikZ? \documentclass[tikz]{standalone} \begin{document} \begin{tikzpicture} \draw[ domain=0:314, samples=10000, trig format=rad, declare function={ t1(\x) = 3.14 * \x; x(\x) = cos(\x) + cos(t1(\x)); y(\x) = sin(\x) + sin(t1(\x)); } ] plot ({x(\x)},{y(\x)}); \end{tikzpicture} \end{document}

I am currently writing a linguistic document for which I will need to include multiple tables showing the inflection of various classes of word. I want to be able to have multiple noun declension tables, adjective declension tables, and verb inflection tables throughout the document, and for each table of a given type to have corresponding columns with the same widths (if I overlay one table of a given type over another, the column edges should line up). I.e. I have tables belonging to three types, A, B, & C. Each table of a given type has the same number of rows and columns. I want to ensure that each table of a given type is rendered with the same column widths (ideally this would not have to be set manually by me, but determined based on the widest text placed in a given column in a table of that type). The different types of tables may be interspersed with each other, and tables of a given type might occur in different chapters, so any solution would need to be able to handle that. A minimum example: \documentclass{article} \setlength\parindent{0pt} \begin{document} \begin{tabular}{ r l l} Case & Singular & Plural \\ \hline Nominative & -foo & -bar \\ Accusative & -foo & -bar \\ Genitive & -foo & -bar \\ \end{tabular}\\ Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aenean dictum, mauris id cursus interdum, ligula libero tristique nisi, eget accumsan risus diam et erat. Nulla dignissim neque a accumsan tincidunt. Integer eleifend vel ante porta fringilla. Praesent et venenatis enim, eget vehicula lorem. Curabitur cursus condimentum sagittis. Curabitur eget facilisis massa. Phasellus vitae scelerisque neque. Pellentesque quis magna sed neque mattis tincidunt.\\ \begin{tabular}{ r l l l l l l} Tense & 1sg & 2sg & 3sg & 1pl & 2pl & 3pl \\ \hline Present & -foo & -foo & -foo & -bar & -bar & -bar \\ Past & -foo & -foo & -foo & -bar & -bar & -bar \\ Future & -foo & -foo & -foo & -bar & -bar & -bar \\ \end{tabular}\\ Donec vitae risus id eros consectetur gravida eget nec erat. Fusce condimentum, sapien id vulputate ultricies, felis lacus sagittis elit, sit amet accumsan purus ante dapibus magna. Cras nec quam ac diam dapibus elementum sit amet vitae turpis. Praesent bibendum eleifend imperdiet. Etiam sit amet congue libero. Donec at mauris vitae mi tristique rhoncus sit amet sed turpis. Phasellus sed velit nec sem sodales molestie. Ut gravida, lorem at euismod elementum, lectus massa viverra dui, a ultrices arcu nulla nec arcu. \\ \begin{tabular}{ r l l} Case & Singular & Plural \\ \hline Nominative & -a-really-long-ending & -bar \\ Accusative & -foo & -bar \\ Genitive & -foo & -bar \\ \end{tabular}\\ Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aenean dictum, mauris id cursus interdum, ligula libero tristique nisi, eget accumsan risus diam et erat. Nulla dignissim neque a accumsan tincidunt. Integer eleifend vel ante porta fringilla. Praesent et venenatis enim, eget vehicula lorem. Curabitur cursus condimentum sagittis. Curabitur eget facilisis massa. Phasellus vitae scelerisque neque. Pellentesque quis magna sed neque mattis tincidunt.\\ \begin{tabular}{ r l l l l l l} Tense & 1sg & 2sg & 3sg & 1pl & 2pl & 3pl \\ \hline Present & -foo & -foo & -foo & -bar & -bar & -bar \\ Past & -foo & -foo & -something-that's long & -bar & -bar & -bar \\ Future & -foo & -foo & -foo & -bar & -bar & -bar \\ \end{tabular}\\ \end{document} The first and third table are of the same type, and the second & fourth table are of the same type. Because of this, the two Singular columns of the first and third tables should be of the same width, but because the third table has a longer ending in the table, its Singular column is much longer. Likewise, the 3sg columns of the second and third tables should have the same width, but in the fourth table it's much wider. As seen here, tables of a given type may be separated by other tables (including other tables of a repeating type). There might also be chapter/section/subsection boundaries between the tables of a given type.
