Subject: question about MP drawing with dir
Date: Thu, 24 May 2018 21:01:59 +0200 [thread overview]
Message-ID: <838666be-6ec5-317b-044a-d4d933b41455@gmx.es> (raw)
Dear Alan,
I have the following sample (as I wrote, this is addictive ;-)):
\startMPpage
draw fullcircle scaled (.06TextWidth - .05LineHeight);
for m=1 step 2 until 10 :
path s ; s := (dir30--dir150--dir315--dir90--dir225--cycle)
scaled m;
n := (m * 50) ;
o := (m / 5) ;
for i=0 upto n :
draw textext("\utfchar{"EB09}")
scaled (o * .025) shifted point (i/n*length s) of s ;
endfor
endfor
\stopMPpage
dir seems magic to me. I don’t understand how it works, not even how it
can be used for drawing not having an origin.
Would it be possible that all stars are vertically centered?
How should be the path defined?
Many thanks for your help,
Pablo
