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 👇

ICARE was created in collaboration with @WithLoreCo and the World Labs team using Marble and Spark 2.0 Developed by: • @LoicPix (Art & Animation) • @itsnicholash (World Design & UI Design) • @PendingReallity (Technical Art Direction & Engineering)

Built using Spark 2.0 LoD for 3D gaussian splat rendering on the web 🤩🌎

Spark 2.1.0 is out! Enjoy! ⚠️ This is a must upgrade to keep your content working on Chrome 149 onwards and other browsers that rely on ANGLE. They made “packed” a reserved keyword causing shader compilation errors in older @sparkjsdev versions. Full changelog: github.com/sparkjsdev/spark/…

This raspberry splat from Dany is incredible. Link to hosted version with @sparkjsdev in reply.

Dormant Memories — a gallery regrouping my recent experiments built from real-world captures, reconstructed as 3D Gaussian Splats, and in many cases manipulated using @theworldlabs' Marble. smallfly.com/dormant_memorie… Everything is built with Spark, the 3D Gaussian splat renderer released by World Labs. It runs in the browser and can be experienced across devices: desktop, mobile, and headsets like Apple Vision Pro and Quest 3. This work comes out of something I've been exploring for a few years now: capturing fragments of the world (places, objects, moments...) and turning them into spaces that can then be revisited, manipulated, and explored in real time. What particularly interests me here is the process of creating alternate versions of the same place; starting from something that physically exists and using it as a base to explore variations, instead of generating from scratch. These explorations are part of what we do at @bonjourdpt... same tools, same curiosity, same collaborative energy that shape the studio's work on interactive and immersive experiences. Some of these experiments were featured as part of the Spark 2.0 release by World Labs. Their technical blog post is a must-read; link in the thread ↓ These are experiments. They aren't fully optimized, they aren't bug-free, and the UX has rough edges. The goal is to explore, test, and learn. #GaussianSplatting #3DGS #pointcloud #WorldModels #sparkjs #threejs

STARSPEED by @jamesckane is a multiplayer shooter with a 10-song synthwave OST and gripping story. 🛸 It uses Spark and the .rad format to stream massive 100M splats with zero friction. Created with Marble, Three.js and Blender. Play it here: starspeed.game/

Spark 2.0 was built to make massive-scale 3D open and accessible on the web. It’s exciting to see builders already using the LoD system to stream high-fidelity worlds, like the 100M splat environments in STARSPEED. Take a look at how creators are shaping the future of 3D. 🧵👇

Spark 2.0 is a complete solution for streaming and rendering 3DGS worlds on the web. 🌍 With a programmable GPU engine, .RAD streaming, and virtual memory, we're making 100M splat scenes accessible to everyone, on any device. Start building today: sparkjs.dev/

The final piece: Spark adapts OS-level Virtual Memory to the GPU. We manage a 16M splat physical pool that swaps 64K "pages" of data in and out from .RAD files using an LRU eviction strategy. This is how we render infinite, composite worlds on a mobile device. Demo: wlt-ai-cdn.art/spark-2.0/260…

Existing formats like .PLY and .SPZ aren't built for streaming. We developed .RAD: a spatially partitioned format that lets you see a 64K coarse version of a scene instantly while refining details as you move. Refinement happens in real-time, prioritized for your view. ⚡

Spark includes two "training-free" algorithms to build these hierarchies: Tiny-LoD for fast, on-demand use in the browser, and Bhatt-LoD for high-quality offline processing using statistical shape similarity. No reference images needed—just raw 3DGS data. 📁 Demo: wlt-ai-cdn.art/spark-2.0/260…

To keep the main loop smooth, Spark updates LoD updates asynchronously using Rust compiled to WebAssembly. We also use fixed foveated rendering to bias the splat budget toward the center of your view. More detail where you look, less where you don't. 🎯 Demo: wlt-ai-cdn.art/spark-2.0/260…

Performance Magic 🪄 Spark maintains a steady frame rate by computing "slices" through the LoD tree. By setting a budget (500K to 2.5M splats), we ensure a constant workload for the GPU regardless of scene size. You can trade detail for FPS in real-time to fit any device.
