Sparkjs streaming+LoD is now stable(ish). This flythrough is over 100m splats rendered in browser. The splats are chunked into ~900 pages with a working set of around 16million splats. I think it can handle arbitrary size worlds now. Anyone have a 1 billion splat I can try?

Multi-splat object LOD test in sparkjs. 7 AI generated worlds, 12.5m total splats. Pretty consistent 120 fps on my laptop.

!! 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!)

Total insanity. This is using an adaptive LOD scheme in sparksjs (not merged yet). The entire scene has 16million splats and this is real time navigation ... 😱😱

AI aided 3D world building is getting ridiculous. This is a large, multi-room gaussian splat (~6million splats). Has streaming, LoD, character support, spatial audio, physics, collisions, VR support, and streaming video. Audio on ... Great place to watch a movie :)

<Splat src={url} /> is now in drei. this is the Kevin Kwok variant. i added data re-use w/ multiple splats, splats can freely move (tied into physics for instance), depth sort is OK, colorspace, support for alphatest and alphahash, and integrated into react-suspense.

Some of the large scene's being generated are really unbelievable. This is a generative 3D splat, not 2D video. The full scene is likely over 50million splats. You can see some stitching inconsistencies from the final v2v pass. Also nice music :)

I like big splats and I cannot lie SparkJS getting LOD support is gonna be a big unlock for massive 3d scenes — whether captured or generated

Working on a tool to generate low poly collision meshes from gaussian splats. It uses marching cubes and quadric error metric (QEM) decimation. Results are pretty good, it can get a usable sub 10Mb collision mesh from a 50Mb splat.

I've made Gaussian Splat Coloring Book for Vision Pro. Still rough on the edges, but working in splats on AVP is super rewarding, and now I'm thinking about full blown Gaussian Splats editor instead of just a coloring book :D

I've been implementing multi-object combined LODs (actual LODs this time) for gaussian splats. It is insanely cool, due to the way I select LOD's I *always* render the same amount of splats no matter how many splats are in the scene. This scene has 108M total combined splats.

Integration test for all components of a prototype metaverse (protoverse?) Supports distributed hosting of worlds (~300m splats total), streaming, LoD, two way portals, on demand scene loading and collection. 160fps laptop / ~50fps VR. Next up, multiplayer.

I like big splats and I cannot lie. PlayCanvas's new LOD streaming system for 3D Gaussian Splatting is a big deal. It's a key step towards splatting the world and making it explorable. Check out a live demo below in your browser.

Absolutely massive dive into a enormous splat (Mega Hell by Brittani Natali ). It's remarkable we can create scenes this large in a few days. This is an early peak at sparkjs 2.0 that has higher precision, improved paged streaming, updated Bhatt(acharyya) LoD, and a lot more.

Collisions are finally coming! Automatic splat to conversion is tough given how messy AI generated splats are. So I created a simple editor that does down sampling, opacity filtering and then basic marching cubes and the results are pretty OK! 🥳

🎨 Now we can use ZBrush (like) sculpting tools with Gaussian Splats! Just made GPU-accelerated sculpt brushes for real-time splat editing splats: 🖐️ Smudge - Push splats like digital clay 🤏 Pinch - Pull splats inward (SHIFT shortcut) ✋ Move - Gentle repositioning, SHIFT for straight lines 📐 Flatten - Create clean surfaces in any direction 🌊 Relax - Smooth noisy areas, SHIFT to roughen/scatter ✨ ALT restores splats to original positions - like a undo brush! All running on GPU compute shaders for smooth performance even with millions of splats. Finally treating Gaussian Splats like real sculpting geometry 🔥 #GaussianSplatting #3DGS #unity3d #gamedev #nerf #Photogrammetry #ZBrush #worldlabs

Continuing my 3D Gaussian splats pipeline iteration... This time I get closer. Here’s a quick test comparing training steps: 12 million splats + 60k steps vs. 6 million splats at 40k steps. The number of splats clearly impacts the level of detail. But I keep in mind the trade-offs when rendering 3D GS in real-time.
