Thanks! Never been easier to start than right now. This physics engine is a bit opaque in terms of how it works, but I recently wrote about a global illumination approach that uses surfels - I break it down into small manageable pieces, with plenty of interactive visualizations, and it's also in WebGPU! If you have some time, maybe take a look at that and start taking it apart: https://juretriglav.si/surfel-based-global-illumination-on-t...

I actually have an implementation of that too, since I was fascinated by the twisting cloth example, but need to figure out how best to incorporate it, or if it’s better in a standalone experiment.

The excellent 3D demo on that page is CPU based, serial.

These examples are amazing, though compute heavy and built with WebGL, which is less than an ideal fit for it. This website and project have been around for a couple of years, and the web's graphics capabilities have grown since, bumped up significantly by the introduction of WebGPU. And since Firefox introduced support for it in 141 on Windows, and 145 on macOS (see wiki tracking implementation here: https://github.com/gpuweb/gpuweb/wiki/Implementation-Status), it now also enjoys broad cross-platform support (Windows, macOS, Android, iOS, with Linux trailing a bit behind).

I've recently written about another compute heavy global illumination approach, which is all but impossible to pull off using WebGL: https://juretriglav.si/surfel-based-global-illumination-on-t...

After this experiment (and some that are in progress), and some very recent movement on raising the bound storage buffer limit in Chrome (https://issues.chromium.org/issues/366151398), I can't help but feel that we're on the cusp of an AAA-level experience built exclusively on the web. I'm super excited for the future of computer graphics right in your browser.

Thanks! Absolutely, dig in, the code is MIT :). I bet your previous experience would lead to significant speedups/quality improvements somewhere in the bowels of the pipeline. Contribs very welcome, too!

Can we use WebGPU to compute real-time global illumination with surface patches called surfels? Does it look good enough? Is it fast enough? And can we finally construct viable compute-heavy rendering pipelines right here on the open web? Join me on this journey and let's find out!

Hm, I'm not entirely sure if you're being sarcastic or not, but just in case, asking Bing about the menu I get this:

> Chez Panisse is a famous restaurant in Berkeley, California that serves seasonal and organic food1. The menu changes daily and is posted on their website2. Today’s menu for the restaurant (not the cafe) is:

> Fennel and leek salad with rocket, toasted almonds, and salsa verde > Bomba rice cooked with clams and squid; with aïoli > Becker Lane Farm pork loin roasted with Spanish paprika and green garlic; with > braised greens and wild mushrooms > Meyer lemon sherbet with candied kumquats > The price for this menu is $175 per person2.

That seems to be correct.
