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!)

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?

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.

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 :)

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! 🥳

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 ... 😱😱

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.

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 :)

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.

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 :)

The low poly meshes I created are much, much faster with physics / collision than those directly from the splat to mesh translation. Amazing. I now have an end to end workflow for generated 3D worlds with usable collisions. Works great in VR and mobile too ...

✨ Built my own Guassian Splat viewer for my app 🏡 Interior AI It takes splats generated from your interior with the World Labs API so you can walk around them in 3d space It's starting to look much more real than when I added splats 6 months ago, great work 🌐 World Labs!

Most angles have nice consistency in this AI generated 3D room. Objects have pretty OK geometry. Some ghosting. But regardless the pace of these models is just incredible.

The iteration speed with AI is just insane. Brittani Natali made the start scene in just a few hours. The total splat count for all these scenes together is around 400m or so. There is a *lot* to explore. Hosted version up at:

OK, this is insanely cool ... - screen mirroring into the protoverse - Shared multi-player view for anyone in this scene - Not fast enough for video (yet) but good enough for code - can type on laptop and view in VR :)

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

some of these 3D AI generations are getting out of hand. this is a stupidly large splat, it's not real time video.

Another ridiculously large AI generated 3D scene. Tons of detail, and nice stereoscopic audio (turn on sound if you can). Works well in VR (although some quant effects from Spark near the end). Hosted version in reply.
