Show HN: Box2D fluid simulation in WebGL and WASM

Does this work for most people? I’d assume it was just my slightly out of date version of the weird browser Palemoon that makes it throw “SyntaxError: missing declaration after &#x27;import&#x27; keyword” and stay blank white (<a href="https:&#x2F;&#x2F;ibb.co&#x2F;Bj2HHxH" rel="nofollow">https:&#x2F;&#x2F;ibb.co&#x2F;Bj2HHxH</a>) for me, but a dead comment just claimed it’s broken on both macOS and iOS Safari, and Chrome.

&gt; This experiment relies on a lot of new Web Worker functionality (ES imports and requestAnimationFrame). As such, it is currently only expected to work in Chrome&#x2F;Chromium-based browsers.<p>Ah, how was it again regarding IE?

Doesn&#x27;t work on Firefox<p>SyntaxError: import declarations may only appear at top level of a module

Neat. Slightly related, I did a fluid simulation many years ago in JS: <a href="https:&#x2F;&#x2F;asadmemon.com&#x2F;SPHjs&#x2F;" rel="nofollow">https:&#x2F;&#x2F;asadmemon.com&#x2F;SPHjs&#x2F;</a><p>code: <a href="https:&#x2F;&#x2F;github.com&#x2F;asadm&#x2F;SPHjs" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;asadm&#x2F;SPHjs</a>

Nice work!<p>What&#x27;s the benefit of using WebGL compared to Canvas?<p>Does the WASM bring a performance improvement in practice, relative to the equivalent JS library?<p>Keep it up!

That&#x27;s art. Thanks for sharing.

Shows an empty box on chrome linux?

How come only Chrome has whatever feature this needs?

I remember in 2015 when I first saw that go-kart wasm demo. It was exciting. But that was such a long time ago and we are only now starting to see webgpu roll out. I’m really looking forward to the new golden age of wasm and webgpu.
