Here's a bunch of outputs of Chadni patterns on a square plate affected by a sine resonator in the middle of the plate. I integrate image over time to get smoother pictures. Webgl, vertex shader + FBO to store positions of particles

WOW!! THANKS CAMILLE! FBO is a framebuffer object. Not too descriptive, I know :-D It's a way you can render to a texture instead of canvas. Particularly you can store positions and velocities of particles this way: every frame you read them from RGBA values of pixels from one texture, modify, write to another texture.

You’re welcome! Hoo! I really want to learn that! I want to play with recursive shaders too. It looks a bit complex to initialise in raw JS. I’ve to see if it’s simpler with p5 ou three.js. Swissjs looks great for that but not onchain

Shaders in p5 are really simple unless you need precise textures. Which is enough for fractals and not enough for chaotic systems. What do you mean by recursive shaders? Fractals?

the good word is maybe "ping pong shaders". To apply multiple times a same shader
