Developer releases interactive voxel map of Warsaw city centre
Creator builds 3D explorer using open datasets, Minecraft-inspired visuals, and dynamic time/weather controls.
What to know
- A Warsaw city map rendered in voxels with Minecraft-inspired aesthetics, featuring dynamic time and weather controls and pedestrian interaction.
- Built from open datasets (OpenStreetMap), optimized for desktop with mobile support, initial load times noted.
- Launched on Hacker News on November 2, 2026, and subsequently shared across Mastodon and social feeds.

Project details reveal open data sources and design constraints
The creator specified that the map is based on several open datasets including OpenStreetMap for buildings, streets, sidewalks, and trams. The project works best on desktop but has been optimized for mobile use, with an initial load time caveat.
“Works best on desktop, but I tried to make it usable on mobile too. The initial load can take a while. It's based on several open datasets, including: - OpenStreetMap.”

Nice. At first glance looks cool, but then, oh my, some areas are really butchered :S Poor Old Town and Plac Zamkowy - I'm familiar with the area and at first was scanning trying to find it visually by the features I know are there, but then in this model it's very different (wrong color, many more floors in this model, a 20-story building where…

Looks great! Sad that could not find that my favourite thing from warsaw trip, this really long residential building that had actually its own wikipedia article and was called "dachshund" :D

background
Developer releases voxel map of Warsaw on Hacker News — A creator posted "Show HN: Warsaw in voxels" showcasing an interactive 3D map of central Warsaw built with Minecraft-inspired voxel graphics. The project allows users to explore the city, change the date, time of day, and weather conditions, and click on pedestrians to control them.

What a cool project. Without any knowledge on the mentioned datasets: how generic is the approach you used for building the voxel world? Can this be applied to other cities as well?Does this bring us a step closer to a fully virtual Minecraft world?!

Super neat project but I am getting fractional (<1 FPS) frame rates in FF on Linux. Granted, this is an older AMD PC and certainly no power house but it used to run actual Minecraft just fine.

I really enjoyed visiting Warsaw, I went there for work a few years ago and didn't really know what to expect.If you ever have the chance, I highly recommend the Warsaw Uprising Museum.

It's almost unusably slow on my laptop. 3080ti mobile, windows 11, chrome. I opened the profiler and the update appears to be fast enough; roughly hitting 30fps, but there are massive gaps between updates and the actual frame time seems to be about 120ms.Other than that, neat :)

It'd be cool to see these taken to the next level by showing actual live updated public transit and car traffic

Mobile version reloads, imho it is too heavy for Safari.Well done.As default weather - I would prefer sunny day instead of rain…

There are quite a few such other projects, e.g. Streets of Prague (https://beta.streetsofprague.com/), were one can explore Prague in a top-down GTA2-like mode, based on real data.
