how about WebGPU

Will Unity support Progressive Web Apps (https://learn.microsoft.com/en-us/microsoft-edge/progressive-web-apps-chromium/) with WebGPU support? I.e. things like installation and storage are very important, WebGL suffered from a cache clear re-download no install scenario that made it impossible to support on commercial/corporate apps along with local storage issues, I was doing some Unity work for the Mining Industry for pit management (lifetime voxelization of pit areas) as a government department contractor and it was one of the big issues along with threading and the speed (solved with WebGPU) that we had to remain desktop bound. The mining company really wanted a browser based solution.

If Unity doesn't directly support PWA it would be great if the WebGPU builds were componentized and not monolithic so they can be used as REACT/Angular components in a SPA PWA.

Seems the 4GB per tab limit has been solved so that is good, years since I worked commercially on it with Unity, 16GB is probably enough, it would be nice to have more with some commercial applications in Mining I worked in the models were extreme and some are in other industries.

Please note this though still applies as of '22 it seems, hope Unity are not just relying on the heap assume Google would have warned about this

"There are different memory limitations for different kinds of memory. The 4G limit is on heap. There is 16G available for fixed arrays (recently improved from 8G), and there is 16G available for the new "web assembly language". The 4G heap limitation is here to stay, apparently. It has to do with making Chrome more efficient for "ordinary" browsing. Google "pointer compression" for a full discussion. If you are running into a 4G limit, then you are running out of heap, and you either have to re-architect your application (as we did) or give up on Chrome."

Thanks!

 

Asking naively, but I assume you took a look at the PWA template for WebGL?
https://docs.unity3d.com/Manual/webgl-templates.html

 

I think we did, but I remember the biggest problem was that Unity embedded WebGL could not interact with the web page natively in Javascript, you had to use these Unity player calls and it was really a bit of a bad experience, web developers are really against it and it was very heavy with no ability to do components, this along with other storage issues made it a no starter for commercial/corporates. I hope Unity will understand that there is limited use just embedding a monolithic application in the browser compared to something that interacts directly with Javascript / HTML on an SPA in a PWA fairly natively like a REACT/Angular component.

 

Organizational question: are these changes planned for Unity 2023.3 or is there still hope that this could happen with Unity 2023.2 despite the fact that the beta is well advanced?

 

Any news about this series of updates ?

 

Would WebGPU after these changes work with the unity graphics for entities package (relies on compute shaders)?

 

This is a very exciting news ! Thank you for all your hard work ! Can’t wait to try it !

 

As VFXGraph are in preview for mobile anyway. In the same sense I wish unity would just release VFXGraph for webgpu as is. And we can face any limitation in the meantime

 

Will GPU-Driven-Rendering be supported in WebGPU?

Thank you very much

 

I don't have to say it to you but for the sake of anyone in this thread; generally speaking, alleviating CPU-bottlenecks on thWeb platforms is basically the holy grail of performance improvements due to the single-threaded limitation of it.

 

Does this mega branch got merged ?

Also, do you know if a Unity blog post is planned about the development progress of the integration of WebGPU into Unity ? I’m very interested of the different challenges you have encountered.
