Re: [NTG-context] Metapost Animation of Sine
Hi Jeroen,
Unfortunately I am not familiar with Tikz, since all my documents use what is
built-in ConTeXt and Metapost…
That being said I am sure someone on the list can help you with Tikz module.

Re: [NTG-context] Metapost Animation of Sine
Hi, both solutions are great! This is what I had in mind, a rolling sine.
Is there a way to get the same result with the Tikz module?
\usemodule[animation]
\setupinteraction[state=start]
\starttext
\input tufte
\framed{
\startanimation[menu=yes,framerate=40]
\dorecurse{50}{\expanded
{\startframe
\startMPcode
numeric u, omega, mylength, tt ;
u := 2cm ;
omega := 4 ;
mylength := 3.141596 ;
tt := \recurselevel ;
path p ;
p := (0u,sin(omega*(mylength/100)*tt)*u) for i = 1 upto 100 :
.. (((mylength/100)*i)*u,sin(omega*(mylength/100)*(i + tt))*u)
endfor ;
draw p withpen pencircle scaled .5pt withcolor darkred ;
\stopMPcode
\stopframe}
}
\stopanimation
}

Re: [NTG-context] Metapost Animation of Sine
Hi,
Adding to my previous message, if you are looking for an animation of the wave
equation for a string with fixed endpoints, one has to use something like the
following:
% begin wave-sine-string.tex
\usemodule[animation]
\setupinteraction[state=start]
\starttext
\startTEXpage[offset=2pt]
\startanimation[menu=yes,framerate=10]
\dorecurse{101}{\expanded
{\startframe
\startMPcode
numeric u, omega, mylength, tt, N ;
u := 2cm ;
omega := 4 ;
mylength := 3.141596 ;
tt := \recurselevel - 1 ;
N := 500 ; % number of steps
path p ;
p := (0u,0u) for i = 1 upto N :
--
(((mylength/N)*i)*u,cos(omega*(mylength/N)*tt)*sin(omega*(mylength/N)*i)*u)
endfor ;
draw p withpen pencircle scaled .5pt withcolor darkred ;
\stopMPcode
\stopframe}
}
\stopanimation
\stopTEXpage
\stoptext
% end wave-sine-string.tex

Re: [NTG-context] Metapost Animation of Sine
Hi,
I wonder whether something like the following is what you are looking for:
% begin wave-sine.tex
\usemodule[animation]
\setupinteraction[state=start]
\starttext
\startTEXpage[offset=2pt]
\startanimation[menu=yes,framerate=10]
\dorecurse{100}{\expanded
{\startframe
\startMPcode
numeric u, omega, mylength, tt ;
u := 2cm ;
omega := 4 ;
mylength := 3.141596 ;
tt := \recurselevel ;
path p ;
p := (0u,sin(omega*(mylength/100)*tt)*u) for i = 1 upto
100 :
..
(((mylength/100)*i)*u,sin(omega*(mylength/100)*(i + tt))*u)
endfor ;
draw p withpen pencircle scaled .5pt withcolor darkred ;
\stopMPcode
\stopframe}
}
\stopanimation
\stopTEXpage
\stoptext
% end wave-sine.tex

Here is another way to do your animation. This is doing something, but I guess
not what you want. Could you describe what do you have in mind ?
\starttext
\dorecurse{7}{ % 3180
\startMPpage
myvariable := #1 ;
path p;
numeric n, u;
u := 1cm;
n:=myvariable*u;
p := (-90/360*1.5cm,-0.9cm) for i = -90 upto 630: ..
(i/360*1.5cm,0.9cm*(sind(i))) endfor shifted (n,0);
draw p;
\stopMPpage
}
\stoptext

[NTG-context] Metapost Animation of Sine
I use this small animation to enlarge a circle
\usemodule[animation]
\setupinteraction[state=start]
\starttext
\startanimation[menu=yes,framerate=10]
\dorecurse{7}{\expanded
{\startframe
\startMPcode
path p;
numeric n, u;
u := 1cm;
n:=\recurselevel*u;
p := fullcircle scaled n;
draw p;
\stopMPcode
\stopframe}}
\stopanimation
\stoptext
This I use to draw a sine
\starttext
\startMPcode
draw(-90/360*1.5cm,-0.9cm) for i = -90 upto 630: ..
(i/360*1.5cm,0.9cm*(sind(i)))endfor;
\stopMPcode
\stoptext
When I put it together to animate the sine as following, it does not
entirely create the sine animation I am looking for
\usemodule[animation]
\setupinteraction[state=start]
\starttext
\startanimation[menu=yes,framerate=10]
\dorecurse{7}{\expanded
{\startframe
\startMPcode
path p;
numeric n, u;
u := 1cm;
n:=\recurselevel*u;
p := (-90/360*1.5cm,-0.9cm) for i = -90 upto 630: ..
(i/360*1.5cm,0.9cm*(sind(i))) endfor shifted (n,0);
draw p;
\stopMPcode
\stopframe}}
\stopanimation
\stoptext
What better way can I create a sine animation with Metapost?
