I write software, usually graphics related. Working at Snap on PlayCanvas. Previously Bloomberg, Sony, 5dt.
That's cool, I had no idea braintrance were using our viewer.

We're actually busy working on VR controls right now. Hopefully we can update the viewer within the next week.

Yes VR is supported! Just follow the link and choose one of the icons at the bottom of the screen.

Our VR mode is not great though, needs work.

If you have a beefy headset you might be interested in trying this scene, which just blew me away when I tried:

Some of the specular lighting has an unpleasant blotchy appearance.

This is unfortunately quite common in scenes with shiny objects, especially cars.

I really hope "the researchers" find a way to improve this particular training artefact.

It's an amazing achievement, congrats!

We're going to try stochastic alpha & TAA. No sort, and then we could use GPU viz.

I'm personally excited about 4dgs/3d videos. I imagine this being used similarly to videos and also working very well in AR.

So you're right there are restrictions (I agree calling GS 3d photos!), there seem to be surprising uses. We just need to improve performance now. I am confident we can!

Another thing I wasn't expecting is that GS holds up very well under scrutiny, like VR. Where the illusion breaks down with traditional polygons (think because surface shading), GS doesn't. This scene on AVP blew me away! superspl.at/view?id=9fd6...

What I didn't foresee is how useful (and cheap) it is to bake complex models down to GS, mainly for product viz, e-commerce etc. For example this superspl.at/view?id=95f1.... Currently it's 6MB, we'll soon get that down to 1.5. A user being shown this instead of photos is a huge win.

Quick and fun little test. It's cool to see post-FX like flares/glow are capturable. www.epigraph.us

I'm so happy to find someone else doing this too! I've been shooting this way for years, but usually when I suggest it to other photographers they seem to get upset. 🤔

And for reference, here is the same rendering, but at retina display resolution:

The advantage of this approach is:
- no need to sort gaussians (which we currently do on CPU, terrible for large scenes)
- gpu now generates a z-buffer, so early out is possible and other z-culling approaches

Who knows, perhaps we could combine stochastic alpha and blended alpha...

Just a pity about wgsl

Wait, you're playing on pc or ps?

I had no idea you did this - super cool!
