Anyone ever made modulating lines like AE’s Modulation plugin or Omino Diffusion in TouchDesigner? Interested to know if someone has replicated it or made something similar.

I’m not sure how they generate the lines, but it looks like they mask them out to the shape of the head.
So think you’d want some sort of light/dark mask to determine where particles are visible. then a way to generate the particles / lines. They seem to flow with the silhouette of the neck and head a bit, not sure how much of that is playing with the seed value until it looks right vs manual control but you can see plenty of places along the edge of the face where the lines break off and stop also, so some masking happening for sure.
I cooked this up in td, it’s going about it in a different way more than likely, using render buffers to output world space position, and tangent/bitangent which combined with a noise texture down stream can displace the points along the directions of the surface, or at least that’s the idea:
render top inherently creates “shadows” where geometry on the other side is not visible because it is on the back side. So you can move the camera around to change the look and feel.
The trick to getting lines that are denser in one direction than the other are to resize the renders on one direction different from the other:
Here’s what a bit looks like with some parameters animated.

One last trick, you can rotate the 3 texture buffers by a certain amount before the res resize happens, this will rotate your “dense lines” into any other direction you please.
Hi Lucasm,
Excellent effort. I really appreciate your response as well. I’ve downloaded your project file so I’ll work with it and post the changes I’ve made back here when I get around to it. I’ll try it with a moving person as well (video).
I like your addition of changing the direction of the lines as well.
