Hi !

I would like to programmatically draw a bezier curve that looks the most like a sine wave that has a single wave length of 1000 pixel and an amplitude of 1 (which corresponds to 319 pixels high so that the wave form looks proportional, just like a sin(x) function drawn on the Desmos Graph App).

Here are the parameters of my bezier curve:

– p1 =… Read more

“Once you’ve drawn…”.

Well, that was my question: how to draw it all at once….

My problem is solved since I eventually found out how to use an array of values that I plot at once using createPath (my array, [],[],true);

Hi,

I created a simple AE animation using the “write-on” effect.

In the “position argument” of the effect, I wrote this expression:

freq=5.5;

amp=100;

veloc=192;

x=time*veloc;

y=amp*Math.sin(time*freq*Math.PI)+thisComp.height/2;

[x,y]

 

This will progressively draw a sine wave from left to right until it fills the… Read more
