Winner Brandon McNulty from the UCI 2026 World Championship in Montreal as a hologram. This is footage captured from 3x GoPros, processed as a 4D gaussian splat, and played back on-site in AR. It actually felt magical to relive that moment.

@jamesckane Love those physics-based interactions! Is there any way to make it "gloopier"?? 🫟

[Jeff Sipko @solo_solipsist]

Caught footage of the 2026 UCI world champion Brandon McNulty on the last corner before the descent! We'll see if this splats...

@jamesckane @nvidia @theworldlabs @sparkjsdev Congrats James!! Awesome work!

4D is the future of media! Congrats to all the winners at Venice! 🎉

A historic moment for spatial storytelling at Venice Immersive!

All three stories created in collaboration with https://t.co/Emvf9zNwIV took home all three prizes at Venice Immersive 2026, with 4D Gaussian Splatting at the heart of each.

🏆 Venice Immersive Grand Prize
The Pigeon Ring
by Yuqi Zhang and Shixin Tao

🏆 Venice Immersive Achievement Prize
Empire at Sea
by Peter Flaherty

🏆 Venice Immersive Special Jury Prize
Out of the Ashes
by @rorycmitchell and @ImmersiveJourno

Congratulations to the directors and teams behind these remarkable works. Stories always matter more than technology, and this moment belongs to the people who imagined and brought them to life. We’re proud to stand behind these pioneers.

For us, these awards mark a moment we’ve been building toward: 4D taking its place in the language of cinema. The Venice Immersive jury’s recognition feels like the opening of a new chapter, and we’re grateful to be part of it. Here’s to even more stories told through 4DGS at Venice next year.

And if you’re at IBC 2026 this week in Amsterdam, you can talk to us in person at Booth 7.B47, where we’re demonstrating an end-to-end 4D Gaussian Splatting workflow together with Dell, NVIDIA and OBSBOT.

@8Infinite8 @krahets @henrypearce4D @saji8k @renbry I first built a CLI pipeline to train 4DGS using spacetime gaussians and forked supersplat viewer to play back the custom format. Then the comfyUI node wrappers were an easy addition! Stuff is all linked off of https://t.co/RL1RfqOGjd (as are demos)

Some 4D gaussian splats from the text-2-4dgs workflow I built in ComfyUI: https://t.co/KNDQu7eNCe

[Jeff Sipko @solo_solipsist]

@8Infinite8 @krahets @henrypearce4D @saji8k @renbry I can confirm that training a Wan2.2 5b Lora does help to maintain identity. I have a ComfyUI workflow that incorporates this if you want to play with it!

[Jeff Sipko @solo_solipsist]

@krahets Great work on this release! I just created some ComfyUI nodes to wrap 4DAnyone to assist with the workflow. 😄

[Jeff Sipko @solo_solipsist]

@DSkaale @freeandeasykid How are you prompting H3 to get full 360 orbits?

[Jeff Sipko @solo_solipsist]

@YeheLiu 4DAnyone is specifically monocular -- you only need *one* camera! (But the caveat is that it doesn't retain identity well)

[Jeff Sipko @solo_solipsist]

@iBrews Oh man, I love the old school vibe of the render man plugin! That is so sick

[Jeff Sipko @solo_solipsist]

@MattYxlr8 @SnipBilly Like this?

[Jeff Sipko @solo_solipsist]

@Peter_Tihanyi I think you've introduced a bug with the OmitUnusedFunctions stuff. It causes an error during assembly that labels aren't defined when I try to assign them to the vectors via .word. I haven't root caused it, but maybe it's because they're in different segments?

[Jeff Sipko @solo_solipsist]

@AskeBay Hey @askebay, are you going to do anything about this situation? So far you've been handling it very poorly...

[Jeff Sipko @solo_solipsist]

@AskeBay I tried to buy a HoloLens from a buyer back in December, but ebay emailed to tell me it was a scam account. Now ebay is trying to get out of doing anything to help me get my money back! ebay protects scammers. 😡

[Jeff Sipko @solo_solipsist]

@AskeBay @AskeBay 's response in private was "You didn't use PayPal. It doesn't matter that wasn't presented as an option and that it was stated the purchase was covered by the customer guarantee. You didn't read the fine print, so tough luck." I reiterate--ebay protects scammers!
