Really cool seeing this on the quest in mixed reality. I put together a quick demo using WebXR (Three.js), Spark (LoD), and Danny’s raspberry Gaussian splat capture.

I made a little gaussian splat game demo set in a world created in World Labs Marble, using three.js + spark + crashcat + navcat, and I made a video about it! On the World Labs youtube channel now: + project github: My interest in game programming started from a place of curiosity after watching videos like SimonDev's three.js game tutorials. I tried to create something of the same spirit for this one :) It's a tour of the building blocks and concepts that come together to build a browser game inside a gaussian splat scene. It covers: - rendering gaussian splats with three.js + spark with level of detail - splat collision mesh generation - splat navigation mesh generation - adding a first person character controller - baking light probes for a gaussian splat to get environment lighting on characters - casting shadows from characters on a proxy mesh - character pathfinding + navigation mesh queries for quest ribbons - a silly prototype fetch quest in the game world to find the missing spaceship keys I don't think the game will win any awards 😛 but I hope it is a fun & useful game technology tour. Enjoy!

Spark 2.0 is here! 🚀 We’re redefining what’s possible on the web with a streamable LoD system for 3D Gaussian Splatting. Built on Three.js, you can now stream massive 100M+ splat worlds to any device from mobile to VR using WebGL2. All open-source. Dive into the tech 👇

AI 3D workflows for web are getting scary good. Here is a demo with a large splat background (+LoD), mesh character, spatial audio, VR support, and lighting. I was able to create it in a few hours (repo in reply). built with Three.js spark World Labs Audio on :)

Molecular dynamics simulations in mixed reality! With Luciano Abriata and Lucien Krapp we’re scaling our multi-user WebXR platform to enable immersive molecular simulations, fully based on web technologies. Stay tuned, lots of cool stuff coming soon! Three.js #WebXR #Quest3

!! I really cannot believe this works. Large splat scene in VR on a Quest 3 using sparkjs. LoD budget is 500k splats. Runs about 30 fps. Full scene is ~6million splats. It's janky (sorry about the controls) But still, just insane this works at all ... (Metaverse is coming!)

Woah, Gaussian splats in mixed reality look so good! Tech stack: lichtfeld studio for splattering training, virtual desktop for PC VR streaming and passthrough MR using a virtual green screen, gracia for VR splat rendering using the green screen background feature

If you got a Quest 3 at launch, give browser-based MR a try with Spatial Fusion - the WebXR experience that I worked on with PHORIA & Lusion™ for Meta! For web devs; mixed-reality on the web has really crossed a threshold in the last year!

A few environments, created locally on my PC in a few seconds each using that cool new Apple image to Gaussian splat tech, stitched together and lit in Octane Render 2026 and combined with a few models made using Hyper3D by Deemos Rodin. Next year is bound to be the year of Generative 3d.

Really happy with how details and materiality of this dress came out in this gaussian splat That velvet sheen is something impossible(?) to capture using other methods 👗✨ 224 images iPhone 15 Pro > RealityScan > Jawset Postshot. #GaussianSplatting #3Dgs

Easily the coolest and most impressive demo of a 4D gaussian splat i have seen so far. Kudos to the team Btw it's directly on their landing page

3d gaussian splatting is fucking cool. And now you can capture real world spaces just by walking around in your meta quest headset. The real-time feedback ensures you don’t miss a spot. Apple needs to get on this asap:

Porting over some HLSL point cloud shaders over to spark, a gaussian splatting renderer for Three.js. Some of the effects look a bit messy with 3DGS, but fun to play around with! Also using their new depth of field here which looks really nice. Demo coming soon!

From 2D video to a very rough 4D Gaussian Splatting POC on the Apple Vision Pro 👀 Took Big Buck Bunny frames, turned them into Gaussian splats with Sharp (Apple), compressed them with PlayCanvas splat transform to SOG, and played all frames via WebXR + spark Still rough and not fully optimized, but wow, dynamic GS in AVP feels wild 🤯 Second part of the video is on my laptop #threejs

Few know this yet, but Hyperfy has built an insanely well-performing WebXR engine. 🔹 Almost 100Hz feel on my Quest 3 🔹 Runs buttery smooth in a browser, standalone 🔹 Even screen recording doesn’t cause noticeable frame drops Hard to believe this is WebXR. Three.js #WebXR 🔗 Link to try it yourself in the comments!

Look at how crispy this 3d gaussian splat came out! The reflections in the painting have me floored. Captured with a Sony a7iii camera and 18mm lens. I posed the imagery using epic's reality capture and trained it with lichtfeld studio. Lichtfeld is my new favorite way to train splats -- it integrates all the latest research and it’s completely free. Also what I love about 3d capture -- you can process old datasets with new algorithms and breathe new life into them.

I went a little crazy with my first 360-drone captured gaussian splat. Of a public park I always bring my daughter to It really is so amazing how much detail a person could capture in 3D with just hobbyist hardware and software

Quick passion demo using threejs spark and World Labs to make this mock up of a conservationist website with a really satisfying mouseover effect. I want to see more technology that helps/honors nature. Play around with it/get the code ⬇️

IK alone can take you pretty far. I put together a really cute demo to demonstrate this. Watch this Panda robot CNC engrave the MuJoCo logo into a curved dome using mink.
