Cannot make a 3d `\mathfrak` label in asymptote

Question

Trying this:

\documentclass{standalone}

\usepackage{amssymb}

\usepackage[inline]{asymptote}

\begin{document}

\begin{asy}
settings.outformat="pdf";
settings.prc=false;
settings.render=1;
import three;
label("$\mathfrak g$",(0,0,0));
\end{asy}

\end{document} 

After running it through pdflatex I invoke asymptote and get this:

This is pdfTeX, Version 3.141592653-2.6-1.40.24 (MiKTeX 22.12) (preloaded format=pdflatex.fmt)

Everything works fine without \mathfrak.

What can I do?

Answer 1

• You have to import the mathfrak module in the asy environment

• Change the settings.render

   \documentclass[border=5mm]{standalone}
   \usepackage{amssymb}
   \usepackage[inline]{asymptote}
   \begin{document}
   \begin{asy}
   settings.outformat="pdf";
   settings.prc=false;
   // settings.render=1;
   // at least 4
   settings.render=10;
   import three;
   usepackage("amssymb");// <--- this line
   label("$\mathfrak g$",(0,0,0));
   \end{asy}
   \end{document}
