Lofi Worlds – Relax to 3D generated worlds in VR

In plain words

Lofi Worlds is a WebXR application that streams AI-generated 3D worlds for users to explore and relax in. Built using Spark, an open-source 3D Gaussian Splatting renderer, the experience lets users interact with procedurally generated environments on Quest 3, Vision Pro, or desktop browsers. Hand tracking enables users to touch the 3D graphics, with optional spotlight mode for focused viewing. The worlds were created by World Labs using text and image prompts, offering an immersive preview of emerging AI-generated spatial experiences.

In the maker’s words, at launch

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…

  Spark, An advanced 3D Gaussian Splatting renderer for Three.js2025 · sparkjs.dev · ▲377

  I'm the co-creator and maintainer of https://aframe.io/ and long time Web 3D graphics dev. Super excited about new techniques to author / render / represent 3D. Spark is a an open source library to easily integrate Gaussian splats in your THREE.js scene I worked with some friends and I hope you find useful. Looking forward to hearing what features / rendering techniques you would love to see next.

  A Marble Madness-inspired WebGL game we built for Netlify2024 · 5-million-devs.netlify.com · ▲616

  Hello HN! We’re a small creative studio specializing in real-time 3D experiences. Netlify approached us to design and build an interactive experience to celebrate reaching 5 million developers. Inspired by the classic game Marble Madness, we created a gamified experience where users control a ball through playful, interactive levels. The goal was to blend marketing content with the look and feel of a game to engage users. The app is built with Three.js [1], using our custom render pipeline and shaders, and uses Rapier for physics simulation [2]. The 2D content is overlaid on the WebGL view…

  Little Procedural Pixel Worlds2022 · jason.today · ▲227

  Took a break from the falling sand simulation blog posts this week to work on another small project. It's a little pixel world generator- each time you visit, you'll see a new little world. I really like this stuff and had a blast building it yesterday!

  I'm an airline pilot – I built interactive graphs/globes of my flights▲1,539

  Hey HN! Pilots everywhere are required to keep a logbook of all their flying hours, aircraft, airports, and so on. Since I track everything digitally (some people still just use paper logbooks!), I put together some data visualizations and a few 3D globes to show my flying history. This globe is probably my favourite so far: https://jameshard.ing/pilot/globes/all If you’ve got ideas for other graphs or ways to show this kind of data, I’d love to hear them!

  Workout.cool – Open-source fitness coaching platform▲827

  I was the main contributor to workout.lol, an open-source fitness app to easily build a workout routine. The project had traction (1.4k GitHub stars, 95 forks, ~20K visits/month), but was eventually sold due to video licensing hurdles. The new owner stopped maintaining it, and the repo went abandoned. Over the next 9 months, I sent 15 emails to try to save it : no replies. Feature requests & issues were ignored. The community was left with a "broken" tool let's say. I couldn't just let it die So I built the new version from scratch with the same open-source spirit, but a better…
