Here is an example of the wave equation (you can tap/click anywhere to create a disturbance): https://visualpde.com/sim/?preset=waveEquation

Very relaxing! Thanks for sharing

This is fantastic, thank you!

EDIT: Just found the repo: https://github.com/Pecnut/visual-pde/

Am i right in that you use WebGL shaders not just for the presentation, but for the simulation as well?

Oh this is not my project. Was just sharing because its cool.

I found it on reddit where some of the creators have shared some info: https://www.reddit.com/r/math/comments/12rslm0/visualpde_ins...

The about page also credits the creators: https://visualpde.com/about/

Oh okay, nice find, thanks for the link!

Thanks for posting this. These visualizations remind me a lot of Steven Lehar's resonance theory of vision. The patterns resemble learned CNN filters, but with symmetry baked in.

It irks me to no end having a TLA used over and over without a definition anywhere in sight. Guessing Partial Differential Equations here?

Jumping ahead with TLAs off the top of my head to reduce future suffering:

ODE - Ordinary Differential Equations

FFT - Fast Fourier Transform

DSP - Digital Signal Processing

What does TLA stand for?

Three Letter Acronym

TLA was also the only TLA i didn't know in this post.
