Image to 3D world: step inside your photo
Start with a photograph or concept image. Turn its composition into a spatial scene you can explore and export with Marble.
Image to 3D model vs image to 3D world
Most “image to 3D” tools turn a photo of one object into a 3D model. This tool does something different: it builds the space around you.
Image to 3D model
One object, usually cut out from its background, returned as a mesh. Good for product shots, game props and 3D printing. If that is what you need, a dedicated image-to-3D-model tool fits better.
Image to 3D world (this tool)
The whole scene in your photo becomes an explorable environment: Gaussian splats (SPZ / PLY), a 360° panorama and a collider GLB. Good for game levels, film previs, architecture and VR.
Which images work best
Spaces, not objects
Interiors, streets, landscapes and concept art of a place give the model depth to work with. A single item on a white background does not.
Clear depth cues
A visible floor, horizon or receding walls help the world extend naturally beyond the frame.

FAQ
Can I turn a photo into a 3D world?
Yes. Upload a photograph or concept image and Marble builds an explorable scene from its composition. You can walk through it in your browser and export it.
Will I get a 3D model of the object in my photo?
No. This tool builds an environment, not a standalone object mesh. For a single object, use an image-to-3D-model tool instead.
Which file formats can I export?
World outputs include SPZ, a 360° panorama and a collider GLB. PLY and high-quality GLB are available through export options. Paid download rights apply; high-quality mesh export requires Pro or Studio and additional credits.
Is it free to try?
Eligible verified accounts receive 30 free credits, enough for a 20-credit Marble Draft. Check the studio for current costs before submitting.
