[NTG-context] Re: Status of Asymptote
Thanks for all the help. I have decided to use Metapost as it is tightly integrated with Asymptote and I find it fun. -- Respect, Shiv Shankar Dayal ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://mailman.ntg.nl/mailman3/lists/ntg-context.ntg.nl webpage : https://www.pragma-ade.nl / https://context.aanhet.net (mirror) archive : https://github.com/contextgarden/context wiki : https://wiki.contextgarden.net ___
[NTG-context] Re: Status of Asymptote
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 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.

I made a module that draws 3D globes with MetaPost and Lua. This was my first step toward drawing general projections. If anyone would like to join this project, I’d love some help. The globes module is only about 300 lines of code, and most of the challenge was hiding paths and parts of paths that are on the back side of the globe. Anybody could get up to speed pretty quickly. (I am completely new to both MetaPost and Lua, so I tried to be very clear in my coding.) My goal is a drawing process which starts with Lua tables containing data in arbitrary coordinates. The data could be any number of dimensions, and need not be rectangular. (For the globes the data is latitude and longitude points on the countries' boundaries.) The tables could be from an outside source (like the geographic data) or it could be calculated in Lua (for graphing functions or doing simulations). Lua does all of the calculations to project this data down to two dimensional, rectangular coordinates. Lua then passes these two dimensional points, or paths made from them, to MetaPost. MetaPost uses the points and paths to draw dots, curves and areas, to place labels, etc. The only transformation performed by MetaPost is the final scaling for drawing everything on the page. You can find the globe module on GitHub: https://github.com/GavinPolhemus/luageo I am relatively new to Git as well, so have patience if you start commenting or contributing there. I’ll learn fastest if there are collaborators!
