Cities that are data, not pictures.
Perplace generates 3D cities from public map data: the street, the facades, the trees and lamps, and buildings you can walk into. One connected world, editable, in private beta with paid pilots for design, game and simulation teams. It is the most ambitious thing I work on.

The catch
Most 3D cities are a pretty picture. Walk up to a door and there is nothing behind it, and nothing in the scene knows it is a door. A game, a design tool or a simulation can't do anything with that.
My part
I design and build the 3D product, its landing and its posts, and every shipped day gets a public note in the changelog. Not every idea survives it: my first pass at hiding covered faces turned 39 draw groups into 1,510. It went in the bin.


Receipts: the public build log
- Day 1 · Jul 24A world engine, built on a knowledge graph.
- Day 46Public demo. A whole city, 60 fps, in a browser.
- Day 54"Try it" opens: describe a world in a text box.
Fifty-four days, fifty-four notes. Go check.
