Marble

Building a 3D environment usually means modeling every surface by hand, and Marble skips that step. Marble is a 3D world generator that turns text, images, videos or existing 3D structures into high-fidelity, persistent 3D worlds you can explore, edit and share.

The worlds stay in place once created, so you can return to them rather than regenerating a scene each time.

Editing tools let you change a world after it is generated, and you can also produce cinematic video from it.

That makes Marble relevant to interior and architectural visualization, landscape concepts and general creative work.

The audience runs from artists to engineers.

There is a community side too.

You can browse worlds other people have made and publish your own.

Marble accepts several kinds of input, which is its most practical strength: you can start from whatever reference material you already have, whether that is a prompt or a photo.
