3D Lissajous expression In after effects
on Apr 5, 2018 at 10:48:40 pm

Hi everyone,
I just came across an old post of this forum;
Which explain how realize this 3d curve generated by an emitter and trapcode particular. what i'm trying to do is a lissajous 3d path in after effects or an emitter wich create a kind of stroke showing the lissajous curve. I was trying to "translate" this math expression( into a after effects expression but i do not manage in this.

Thanks in advance,

Would this help?


3D Lissajous functions have the general form
x = cos(..t)...
y = sin(..t)...
z = sin(..t)...

Sin and cos functions are interchangeble.

x = 0.5cos(5t) + 0.5cos(4t)
y = 0.5sin(5t) + 0.5sin(t)
z = sin(2t)

Hi, thanks Kalleheikki Kannisto for this help. a couple of days ago i managed with this function. what I did is write the expression in the position property of a NULL and after I've linked to this layer the position (xyz) of cc particle word. I change the comp setting with 120fps because the line painted from particle wasn't really smooth.

however, thanks to this help! I'll try to give to this community what I know.




value + [x,y,z]*130;
