Marble (3D World Generation)
A 3D world generation service from World Labs. You give it text, an image, a video, or a 3D structure, and it builds a 3D space you can move around in. It also hosts a gallery of worlds made by other users.
How to try it
Close the welcome dialog and a grid of community-made worlds appears, filterable by All, Stylized, Realism, Interior, Fantasy or Sci-Fi. Click a world to explore it first, then type a description into the 'Imagine a world...' box at the top if you want to make your own. Generating and saving worlds requires an account login, and the interface and input are English only.
