Would anyone know how to make something similar to this using grasshopper? I tried manually modelling but it just isn’t working out how I would like it. I’m new to GH and I found a similar thread on creating a ripple effect. [image] How to add decay to self interfering ripples ! Hey guy…

I’m on R5 so can’t open the file. Don’t worry, I will just comment from the sidelines on this one. I agree it looks more like a visualisation of a constant sound. Perhaps that is because the decay is not significant enough? I agree that the parameters you suggest are probably what are needed. @Jo…

[image] maje90: For a ripple/raindrop i imagine variables like, for each droplet: speed … so energy time elapsed since hit volume (pouring a glass of water from 1cm might have the same energy of a droplet, but the resulting wave is completely different) direction … but this would be overkill… …

[image] Joseph_Oster: In the damped sine wave equation, does energy correspond to Amplitude and volume correspond to Wavelength? … i’m quite thinking the same… more or less… [image] Joseph_Oster: Wave form and propagation are probably among the most studied and best understood aspects of…

[image] maje90: I’m finding a lot of stuff, but it’s incomprehensible for me… complex math. I remember looking at online “textbooks” in the past and being overwhelmed by the complexity. [image] maje90: Maybe it’s easier to just design the animation aesthetically and forget about math/phy…

[image] maje90: Here a small “simulator” using points as droplets. Droplet fall speed is equal to wave propagation speed, so when a droplet is below Z=0 it is projected to XY plane and its Z value used as radius of the wave. Looking again at your brilliant “droplets” animation, the time fact…

Nice elegant definition @maje90 I was inspired to have a play with an iterative version using Kangaroo- Using springs instead of Laplacian smoothing gives a slightly different effect, with more isolated waves- surface_ripples_kangaroo.gh (12.0 KB) Doing it with only existing…

It’s also fun to anchor some of the points within a region to create an obstacle for the ripples to flow around

[image] DanielPiker: Also - have a look at this: 2D Wave Equation / Tim Yates | Observable Being able to do that on an interactive web page is very impressive!

This is even nicer- [image] WebGL Water The trick for the caustics is clever: [image] Rendering Realtime Caustics in WebGL I created http://madebyevan.com/webgl-water/ back in 2011 and I’ve always been meaning to explain how it works. The most intere…
