Here is a trick: pause the simulation and drag the ripples back and forth really fast, it will create a "mega" wave. Then unpause and it will create a massive tsunami

Or pause it and click the water surface 100 times to raise up a lot of potential energy that makes a very profound wave front when it comes down when you start it.

On this note, can anyone recommend basic webgl 2d effects tutorial? I have a super exciting project I'm really close to announcing, but the last step is adding some pretty Animal Well style effects via webgl2, but I know practically nothing about webgl except the very very basics that you learn from webgl2fundamentals.org. Any pointers would be appreciated.

I like https://thebookofshaders.com/ . It’s unfinished and I don’t think it’s been updated in years, but what’s there is pretty good

Webgl2fundamentals is pretty great :)

The "problem" with it is that you only learn about fragment shaders, you should also learn about the WebGL API, and vertex shaders.

... this is amazing!

I can't wait to dig in and figure out how to add effects like this over my 2d content!

Pretty cool how a basic demo like this still feels fresh, even on my old phone. Always makes me want to mess with web tech more.

Is this open source?

Wasnt this one of the demo that Figma co-founder used make a case for web-based editor?

I guess I'm the only one for whom this doesn't work I get:

'Uncaught Error: This demo requires the OES_texture_float extension'

You must be on a very old browser, a terminal browser, ladybird, something like that. PEBCAK. https://developer.mozilla.org/en-US/docs/Web/API/OES_texture...

I'm also getting the error on Android, latest Chrome.

bobajeff · 8m ago

Nope. Using Chrome 136.0.7103.87 on Android.

This has always been my "is webgl working?" test page

By the way, I think it's (2011) not (2010)

Still. My god.

If you are on Android try Kiwi browser to see this

What does Kiwi do different? The water appears to work well on Brave.

5 year old low end Motorola Android with Firefox and ublock. Smooth as a baby's bottom. Genuinely surprised!

Kiwi is deprecated by the way, use Firefox or just use Chrome which is what Kiwi was anyway.
