any image out in the www. I would like to draw the soccerball using
metapost or gnuplot. Then include it in a tex/latex document. I had a 2d
image with points using gnuplot, but it is not mathematically precise. A
better image of better quality and I can use my own machine to create it is
what I am looking for. Someone has helped generate a soccer field in 3d
with metapost, I have created a soccerfield using gnuplot, but I do not
have a nice soccerball to include it. The 3d image hopefully can be used
to make a shirt as many of our students do not like what the designers
provide. A nice accurate picture generated with precision is what is
needed. I appreciate some thoughts as well. There is a soccerball
generated by tikz on stackexchange, but I do not have texlive on my machine
sadly. It is to our advantage to have it on gnuplot or metapost as
students can see the mathematics behind it.
