Below is how I have used Asymptote in the past with the Context filter
module:
download portable ghostsctipt
create dir c:\context\ghostscript and install from
https://portableapps.com/apps/utilities/ghostscript_portable
download non-portable asymptote
create dir c:\context\asymptote and install from
http://asymptote.sourceforge.net/
create file c:\context\asy.bat with context
ASYMPTOTE_GS=C:context/ghostscript/bin/gswin64.exe
C:/context/asymptote/asy.exe %*
test with:
\usemodule[filter]
\defineexternalfilter[ASY]
[filter={/context/asy.bat -tex context -outformat pdf
-outname \externalfilteroutputfile},
output=\externalfilterbasefile.pdf,
cache=yes,
readcommand=\ReadImage,]
\define[1]\ReadImage{\externalfigure[#1]}
\starttext
Testing if we can include an asymptote image
\startplacefigure[location={here}, title={An Asymptote figure}]
\startASY
size(10cm);
import graph;
real f(real x) {return sin(x);}
draw(graph(f,-3,3,300),blue);
\stopASY
\stopplacefigure
\stoptext
OR alternatively:
\usemodule[filter]
\defineexternalfilter[ASY]
[filter={/context/asy.bat -tex context -outformat pdf
-outname \externalfilteroutputfile},
output=\externalfilterbasefile.pdf,
cache=yes,
readcommand=\ReadImage,]
\define[1]\ReadImage{\externalfigure[#1]}
\starttext
Testing if we can include an asymptote image
\startplacefigure[location={here}, title={An Asymptote figure}]
\startASY
unitsize(1cm);
draw((-.1,0) -- (2,0), arrow=Arrow(TeXHead));
draw((0,-.1) -- (0,2), arrow=Arrow(TeXHead));
draw((0,0) .. (1,1) .. (2,sqrt(2)));
\stopASY
\stopplacefigure
\stoptext

It would be nice to either support Metapost 3D or Asymptote. Right now I
generate images separately and embed them in PDF using externalfigure command
which works but I have to maintain all the graphics separately.
It is possible to obtain simple integration for asymptote using the filter
module:
https://github.com/adityam/filter
Using that you could define an asymptote environment so that:
\startbuffer[asymptote-preamble]
....
\stopbuffer
\starttext
\startasymptote
% Asymptote figure
\stopasymptote
\stoptext
saves the content of the asymptote-preamble and the figure in a separate file,
runs asymptote to generate a PDF figure and includes the figure. The results
are cached so the asymptote is re-run only if the content of the figure
environment changes.
A drawback of this approach is that the labels are generated by asymptote. That
means that the font, colors, and any macros needed for the figures need to be
redefined at both context and asymptote end.
