SAM 3D

Meta’s open single-image 3D reconstruction models, released as separate versions for objects and for human bodies.

SAM 3D is a pair of single-image 3D reconstruction models Meta released on November 19, 2025, part of the “Segment Anything” (SAM) family. SAM 3D Objects takes an image and a mask of a target object and outputs that object’s complete 3D shape, texture, and position and orientation in the scene, handling real photos with occlusion and oblique viewing angles. SAM 3D Body estimates 3D human pose and body shape from a single image, outputting a mesh parameterized by Meta’s proposed MHR (Momentum Human Rig) human body model, and can be prompted with 2D keypoints or a mask. Weights, inference code, and evaluation sets have been released under the SAM License. For embodied AI, it lets a photographed object be quickly turned into a simulation asset, and lets human pose be extracted from images and video of people.

ExampleA photo of a cup on a table is first segmented with SAM 3, then handed to SAM 3D Objects to generate a textured 3D mesh, which is imported into a simulator as a grasping-training asset.
