Meta’s Sam 3D (documentation: https://ai.meta.com/sam3d/ and demo: https://aidemos.meta.com/segment-anything/gallery) generates 3D images from a 2D image, both of which are available models for objects and people.

After selection on the original image, the objects or people are generated in 3D.
Note: Animals are not recognized.

Export video (with possible effects), image, 3D object (ply format) and share by url for scenes and objects, glb export for people.

Free, unlimited, with or without an account (account for url and history sharing).
