We’ve just open-sourced JOSH, our method for 4D human–scene reconstruction in the wild. Huge credit to the first author, my PhD student Zhizheng, who will present this work at @iclr_conf in Brazil next month 🇧🇷 🌐 Project page: vail-ucla.github.io/JOSH/ 💻 Code: github.com/genforce/JOSH A trivia is that this work was finished more than one year ago, and has been rejected twice...Be resilient!

InstantSplat++ is now open source. It is a lightweight library that connects foundation models (VGGT, MASt3R, MAP-Anything, etc.) with the Gaussian splatting family. Given uncalibrated images, it optimizes a 3D scene in a few seconds. Try the demo and code here: github.com/phai-lab/Insta…

@tom_krikorian Ah that’s awesome, great work! High performance splats in RealityKit would be a game changer for visionOS 27. Knowing Personas use them, it must be possible! Are you using LowLevelMesh here?

I've been exploring Gaussian Splatting for a while now and finally have a working version of a viewer working in RealityKit (without Compositor Services) but only on macOS. visionOS performance is just horrible. I don't know how to make that same codebase work on it (yet). Maybe visionOS 27 will help 🙏

@jonstephens85 Sick! Can you get the raw data and process yourself or is it locked into a subscription/license?

Looks like I need to clean my kitchen and start scanning.

Tonight I'll be submitting Splatial to the Vision Pro App Store for review. Here's a sneak peak! Powered by the WorldLabs API and a custom fork of the MetalSplatter project. Hit me up if you want access while I go through the review process!

I really think people don’t yet realize how amazing and powerful FaceTime calls are with Vision Pro.

@RadianceFields Oh, fantastic! Looking forward to that. I built the GitHub sample last night and it took me a moment to adjust & get SH3 looking right. Once I did it was a huge improvement!

@MCDopsa Yeah I should have said that the update should hit the app store in the next couple of days

For anyone trying the update, the SampleApp needs a change to the code in the renderer as it defaults to SH0. The app on App Store has not been updated in ~a year, so you won’t see it there either yet. Looks amazing when you see SH3 on device!

MetalSplatter for Apple Vision Pro released V1.0 adding spherical harmonics (SH 0-3), SPZ support, and visionOS 26 support. MetalSplatter remains free and MIT Licensed for gaussian splatting!

Gaussian splat of friend’s Triumph bike. Captured (1min) and aligned (40 seconds) on iPhone, and processed w Brush (mac) Issues that affected scan were: - reflective surfaces on tank and wheel well - lighting from garage - some blurry images

@jm_tressler Cool, is it your own app / project? Would be excited to learn more

@MCDopsa Yes on device. Been working on some alignment algorithms that incorporate the iPhone lidar.

@Dazitu_616 Can you make a ‘Mask’ for any generated data, allowing you to effectively remove it or not include it?

*Is our result 3D consistent?* Yes! We lift monocular video to 360° and directly train 3D Gaussian Splatting (3DGS) on it. 360Anything generates unobserved regions (e.g., behind the camera) with high consistency which blends seamlessly with observed areas in 3D. (4/N)

📢Introducing 360Anything, our method for lifting any perspective image or video to gravity-aligned 360° panoramas without using any camera or 3D information. This enables consistent novel view synthesis and 3D scene reconstruction. Project page: 360anything.github.io 🧵
