Very nice approach! Using textured primitive is definitly a good idea to decorrelate the visibility information from the texture signal :)

(Plus, I love impostors/billboards, they remind my of my first long paper perso.telecom-paristech.fr/boubek/paper... -- shamelessplug)

It's not easy for sure, chicken and egg problem, which is why our message is at least as much for reviewers then it is for authors! Nobody is to blame individually, it's just sth we should collectively discuss.

I agree, but part of the problem is that what the "average PC in 5-6 years" looks like may indirectly depend on what we do in research. If we only test on these hardware, they'll indeed naturally become the ones people use. :)

Note that 'naga' is the equivalent tool developed by Firefox. It can easily be installed using cargo (the rust build manager): github.com/gfx-rs/wgpu/...

Important notes:
🔹This rewrite is *WIP*, refer to the main section (w/o "next" in the URL) for further chapters.
🔹This only works with Dawn for now because it is closer to what the v1.0 of WebGPU will be.
🔹The accompagnying code "stepXXX-next" is not up to date yet.

PS: I'll be in #Eurographics next week, feel free to get in touch!

Yeah I totally had this issue as well ^^ I can add warnings indeed!

I don't think there is such a toggle, but that would indeed be useful here!

It's very nice that you intend to talk about this with your students 🙏 Don't forget that fossil fuels is not the only issue, rare earth materials (and the rate at which we renew hardware) and water consumption are huge problems too!

A very compelling proof that something isn't going right is to look at the divergence between announced energy reduction plans and the reality of compute providers.

Data comes from provider's own annual reports (that they agreed on publishing a couple of years back, transparency FTW), links⤵️

This report of Wells Fargo is also very informative/worrysome and points to many interesting sources: www.wellsfargoadvisors.com/research-ana...

The most commonly cited source about the growth of energy need for compute is this IEA report: iea.blob.core.windows.net/assets/6b2fd... (screenshot of p31)
