And nearly a Carti post at the top of HN
r/playboicarti is one of my favorite places to go to just turn my brain off and see shitposts that have a certain reminiscence to me, almost a "high school class when the teacher didn't show up" vibe.

It's not a type of radiance field.
It’s literally the name of gaussian splatting. 3D Gaussian Splatting for Real Time Radiance Fields https://repo-sam.inria.fr/fungraph/3d-gaussian-splatting/

I’m fascinated by the aesthetic of this technique. I remember early versions that were completely glitched out and presented 3d clouds of noise and fragments to traverse through. I’m curious if you have any thoughts about creatively ‘abusing’ this tech? Perhaps misaligning things somehow or using some wrong inputs.
There's a ton of fun tricks you can perform with Gaussian splatting! You're right that you can intentionally under-construct your scenes. These can create a dream-like effect. It's also possible to stylize your Gaussian splats to produce NPR effects. Check out David Lisser's amazing work: https://davidlisser.co.uk/Surface-Tension . Additionally, you can intentionally introduce view-dependent ghosting artifacts. In ot…
If you don't know already, you need to leverage this. HN is one of the biggest channels of engineers and venture capitalists on the internet. It's almost pure signal (minus some grumpy engineer grumblings - we're a grouchy lot sometimes).
Post your contract info here. You might get business inquiries. If you've got any special software or process in what you do, there might be "venture scale" business opportunities that come your way. Certainly clients, but potentially much more.
(I'd certainly like to get in touch!)

I believe volumetric is going to be huge for creative work in the coming years.
Gaussian splats are a huge improvement over point clouds and NeRFs in terms of accessibility and rendering, but the field has so many potential ways to evolve.
I was always in love with Intel's "volume", but it was impractical [1, 2] and got shut down. Their demos are still impressive, especially from an equipment POV, but A$AP Rocky's music video is technically superior.
During the pandemic, to get over my lack of in-person filmmaking, I wrote Unreal Engine shaders to combine the output of several Kinect point clouds [3] to build my own lightweight version inspired by what Intel was doing. The VGA resolution of consumer volumetric hardware was a pain and I was faced with fpga solutions for higher real time resolution, or going 100% offline.
World Labs and Apple are doing exciting work with image-to-Gaussian models [4, 5], and World Labs created the fantastic Spark library [6] for viewing them.
I've been leveraging splats to do controllable image gen and video generation [7], where they're extremely useful for consistent sets and props between shots.
I think the next steps for Gaussian splats are good editing tools, segmenting, physics, etc. The generative models are showing a lot of promise too. The Hunyuan team is supposedly working on a generative Gaussian model.

Do you have some benchmarks about what is the geometric precision of these reproductions?

I can see that relighting is still a work in progress, as the virtual spot lights tends to look flat and fake. I understand that you are just making brighter splats that fall inside the spotlight cone and darker the ones behind lots of splats.
Do you know if there are plans for gaussian splats to capture unlit albedo, roughness and metalness? So we can relight in a more realistic manner?
Also, environment radiosity doesnt seem to translate to the splats, am I right?
Thanks
