drawing curves in 2d (or 3d!?)
So, I want to draw some sine waves – would be super cool if they were in 3D – but 2D will do.
I was hoping to animate them.
Any plugins or suggestions?
I can animate the drawing using Write-on plugin – but really I want the sine waves to exist already – and animate them moving…
I’m all up on my maths sine(freq*inc)*amp+c etc etc just need the tools to use it.

I think trapcode’s 3D stroke would do the trick nicely.
It needs masks to operate on though, so you’ll have to draw a nice sine-curve as a mask.
Or: program your sinewave into the position of a Null, convert the position to keyframes, and copy-paste the position keyframes to a mask shape.
see this tutorial on converting between position and shapes:

And these on different methods of animating sinewaves:

That would be great – if only I could somehow animate the mask from keyframes.

What look do you need, a simple sine scrolls from left to right, or more like an actual oscilloscope ?
Should the sines just go up and down, or do you need different frequencies interfering etc.Perhaps it would be easier to find some clean music or sinewave testsignals and use the audio waveform effect on them.
One step further would be to use After Effects’ built-in test-signal audio effects “Tone”, “Modulator” etc. and control the sliders on that (keyframed or with expressions), if you precomp it, you can use it as the sound input of the audiowaveform effect. -
I want to draw curves in 3D using equations – only for my own playing.
In the end I’ve gone for using Particular and a layer emmiter.
