Mini World — 3D World Builder: Grow Your Own Little Planet (Free)
A free browser 3D world builder. Zoom out to a tiny planet, zoom in to a surface you can walk and swim, place 3D models from the asset library, or describe a new object and it is generated into the world.
What it is
Mini World is the 3D world builder itself: a small spherical planet that reads as a globe when you zoom out and becomes an explorable surface when you zoom in. Willow woods, sand and bay are already there; you add the rest.
Build
- Place 3D models from a curated asset library — trees, rocks, cottages, sea life, discoveries
- Generate new ones — describe an object in one sentence and it becomes a reusable 3D component in the library
- Drag objects in, select, move and remove them; the world remembers your placements
- Time and weather run on top: Auto, Sunny, Cloudy, Rainy, Snowy
Play
Walk with WASD or the touch joystick, drag to orbit when zoomed out, steer when zoomed in, scroll or pinch to zoom. Swimming is automatic when you enter the ocean.
Free, and no install
Exploring, playing and browsing the asset library need no account. Sign-in is requested only at the moment you generate a 3D model or save a world.
