World Simulator

World Simulator turns one short line of text into a low poly landscape you can look around. Set a biome, set the weather, set the time of day, then press Generate and the scene rebuilds around you.

The frame shows the Rolling Plains preset under clear skies at midday: a pale rounded hill dotted with small green trees, a flat horizon, and a soft grey sky. Preset chips along the bottom suggest other conditions, such as frozen pine forest at dawn with light snow, volcanic wasteland in an ash storm at dusk, or alien crystal desert under two moons at midnight.

Controls stay out of the way. Biome, Weather, and Time sit in the top left, Orbit and Sound in the top right, and a single text field with a Generate button waits at the bottom. Type your own condition or tap a suggestion to fill the field.

It runs in the browser, with no download and no account.
