Show HN: Lofi Worlds – Relax to 3D generated worlds in VR

16 pixelsynth 0 6/12/2025, 4:35:25 PM lofiworlds.ai ↗

I'm one of the developers of Spark, a new open-source 3D Gaussian Splatting renderer (sparkjs.dev).

While developing Spark, we built a WebXR demo that lets you experience a stream of 3D AI-generated worlds from "inside". These worlds were made by World Labs from text+image prompts last year, and I think it's really cool to imagine what's going to be possible in the near future!

If you have a Quest 3 or Vision Pro, open up lofiworlds.ai in the web browser and make sure to enable hand tracking so you can "touch" the 3D Gaussians :). Tap your wrists together to toggle spotlight mode. The demo works on mobile + desktop as well but 90% of the experience can only be had in VR so I highly recommend dusting off that Quest 3 and trying it in there!

I hope you enjoy some lofi relaxation in the multiverse!
