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?

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 :)

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 :)

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 ... 😱😱

Ahaha, building the protoverse using Cursor from within the protoverse.

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 :)

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.

You can pet the dog now ... All engine elements done, quests, AI NPCs, combat, items, multiplayer, portals, dynamic layers, multi-tilesets, interactive objects. Now it's just level/NPC design, performance/bug testing, and stats tweaking. (built with Convex and Cursor)

This is it, native PCVR on MacOS! The OpenXR SDK can be compiled on MacOS, So I implemented a runtime and a streaming app. Godot supports OpenXR on MacOS so I use it to test my integration. Unity could work too and of course native C++. 1/x

One of the most exciting announcements from the XR team at Unity over GDC last week, is the multiplayer template that sets up all of Unity's multiplayer services for you, including lobbies and spatialized voice chat, all over OpenXR. It even supports hand tracking replication!

If you’re still sleeping on my project Kasping - Take some time to actually research it🫡 The Launchpad (@kingpadfinance) demand to supply is huge. Now on May 1st, our metaverse goes live with controller integration and multiplayer integration to meet web2/3 friends! We will also start a marketing push on May 1st too. You still have a chance to be early.

It was a hell of a year doing statics, but welcome to the new era — things are about to get moving! Please meet Zista, the star of our first real-time, arbitrary-length 6DOF video, streamed on demand from a laptop SSD. Coming soon to PCVR and later for all VR headsets and SDK.

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.
