A rudimentary game engine to build four dimensional VR evironments

I think it's finally time to lock version 0.2 of my 4d side project. (Since previous Show HN a couple of years ago: https://news.ycombinator.com/item?id=37100760 I scrapped lots of stuff and concentrated on making a javascript "game engine") The sole purpose of this project is to explore whether it's possible to make the human brain spatially aware of four dimensions using Virtual Reality. It’s my first ever game project, my first time using Unity, first time writing C#, and my first anything with WebXR, so please be gentle! To manage expectations, it isn't visually pleasing…

A rudimentary game engine to build four dimensional VR evironments launched on July 19, 2025 with 39 votes, #612 of 9,224 launches that month and more than 90% of that year's launches. The site was still online in September 2026, 1 year on.

In plain words

A JavaScript-based game engine for creating four-dimensional virtual reality environments. Built in Unity with WebXR support, it allows users to define 4D objects and behaviors while exploring them in VR to develop spatial awareness of four dimensions. The project is an experimental exploration rather than a polished product, requiring manual study of 3D slices of 4D objects to understand the concepts presented.

Hypershack is a standalone, private space designed for tinkering and learning with 4D objects in Virtual Reality. You can also select “easy mode” that lets you only make 45 degree simple rotations to help you say oriented. when you open Hypershack 0.2, you are provided predefined levels of a simple game where you need to find hypergems (red fivecells) within a tesseract. You can create your own 4d environments and games by defining the objects in json and specifying the object behaviour in JavaScript, see api documentaion here. There are some issues with copy-pasting to unity WebGL games. So unfortunately the process of editing the JSON in game is a bit cumbersome and you need to upload the…from brainpaingames.com

    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…

  • Hey HN! Introducing Trickle Magic Canvas: the world’s first Agentic Canvas, where you can visually co-create apps and websites with AI, from idea to production. Why is a canvas better? Most AI tools today rely on linear chats or text prompts. We believe that limits creativity and clarity. Canvas changes the game. 1. Every version & page at a glance. Each page and sub-page lives on a timeline. You can quickly browse, edit, and preview progress like a living, visual document — no more digging through chat logs or scattered states. 2. The canvas is the context. Unlike linear chats, you can…

  • Today marks ten years, 3653 consecutive days, of running at least one mile every day under the USRSA rules [1]. To celebrate, I built an interactive dashboard that turns a decade of GPX files into charts you can explore. Running has truly changed my life: I've made lifelong friends, explored beautiful places, and more importantly invested into my own health and fitness, which I'm starting to see the positive benefits as I get older. The stack is pretty simple: a NextJS app, with a Postgres database to keep all my running data, and all the stats are pre-computed and cached in Redis, so I…

  • Made this website as an exercise in vibe-coding and GCP. It was posted about a few times around the internet, on sites like Morning Brew (https://www.morningbrew.com/issues/business-buzzkill), MetaFilter (https://www.metafilter.com/209703/Draw-A-Fish), boingboing.net, etc. I think it's cute! I built a basic CNN trained against penises and swastikas, and then anything that doesn't hit the 63% confidence score gets sent to a mod queue, a vibe-coded fish-tinder…

  • Hi HN - I made a site that takes a UK postcode, grabs the local MP's information and generates an AI mockup of what their ID might look like. It's a small, silly protest at the stupidity of the Online Safety Act that just came into force. edit - My open AI credits got hugged to death, please use a known postcode (like one from Kier Starmer's constituency, WC2B6NH) in the meantime.
