Describe a town, generate a starting point, then shape the layout yourself.

Urban Designer showing generation controls and a command field beside a 3D neighborhood — **From instruction to a visible place.** Generation controls and a command field sit alongside the town they shape.

Get the first version into the world

A town takes shape through many small placement decisions. Urban Designer explores how to get an initial layout on screen sooner, so a creator can spend more of the session judging the composition and trying ideas.

The tool combines Gemini-powered natural-language input, an L-system for procedural generation, and interactive layout controls. The central promise is a useful starting point that the creator can continue to direct.

Turn an instruction into a scene

I built the Unity tool and connected it to the Gemini API through a Node.js backend. Natural-language commands feed into world-building operations such as placing objects, scattering assets, and generating houses and trees.

Those operations give the AI output a concrete job inside the scene. Procedural rules handle repetition across a town, while the interactive controls let the creator make local decisions about the result. That balance matters: an interesting generated layout still needs a human eye.

An isometric neighborhood of houses, roads, and trees generated in Urban Designer — **A scene to work with.** Houses, roads, and trees form a starting layout that the creator can inspect and continue to shape.

Keep the creator in the loop

Generation and manual layout design belong in the same workflow. A creator can explore a broad arrangement and then work with its individual parts, rather than treating each generated result as a finished answer.

The downloadable project is available on itch.io and listed as in development. It brings an AI service, procedural systems, and editable 3D interaction together in a working prototype.

An idea you can edit

The strongest use of generation here is to make exploration easier. Urban Designer puts a layout in front of the creator and gives them a way to keep shaping it.
