What is SAM 3D?

SAM 3D is Meta's open source single-image3D generationmodels, you can quickly generate high-quality textures and materials from a single 2D photo. 3D modelIt covers two major scenarios: generalized objects (e.g. furniture, commodities) and human posture reconstruction. Its core technology ensures that the physical details of the model are realistic (e.g. object concavity and convexity, human body muscle lines) through spatial location-semantic joint coding, and at the same time relies on the millions of annotation data engine to solve the problem of real-world data scarcity, with the performance reaching the industry's leading level.

The model supports interactive cue inputs (e.g., segmentation masks, 2D keypoints) for precise control of the generated results, and has been integrated into platforms such as Quest 3 and Horizon Worlds, where it can be called on-demand via an API by developers ($0.02/model), with a real-time SDK for mobile coming in 2026.

Whether it is e-commerce virtual try-on, AR/VR content rapid production, or film and animation prototyping, SAM 3D can significantly reduce the threshold and cost of 3D creation, and its open-source ecosystem promotes the benefits of the technology, which is a cross-industry digital transformation tool.

Core features of SAM 3D

1. Single Figure 3D Reconstruction
   • importation: A single 2D photo (e.g., a picture of a product taken with a cell phone, a picture of a person).
   • exports: 3D models with textures, materials, 360° rotational view, and realistic physical details (e.g., bumpy surfaces, human muscle lines).
   • Technical Highlights::
     • Joint spatial location-semantic coding: Predicts the 3D coordinates and surface normals of each pixel, ensuring that the model is physically correct.
     • Data engine driven: Through crowdsourced scoring + expert correction, nearly 1 million images were labeled to generate 3.14 million 3D grids, solving the problem of real-world data scarcity.
2. Human Posture and Body Reconstruction (SAM 3D Body)
   • Supports abnormal poses, occlusion, and multi-person complex scenes with stable output results.
   • Can be prompted to enter: Users can interactively guide model predictions through split masks, 2D keypoints, and other interactions to improve accuracy and controllability.
   • Bone-Soft Tissue Separation Modeling: Adoption Meta Momentum Human Rig (MHR) format that decouples skeletal structure from soft tissue form to enhance interpretability.
3. Efficient Reasoning and Integration
   • tempoThe NVIDIA H200 GPUs are capable of processing a single image containing 100+ objects in just 30 milliseconds; with about 5 concurrent targets in the video, it can still be processed in near-real time.
   • API Calls: Integrated into Quest 3 and Horizon Worlds authoring tools, developers can call the API through the Edits and Vibes apps for per-volume billing ($0.02/model).
   • Mobile Support: A real-time mobile inference SDK is scheduled for release in Q1 2026.

Scenarios for SAM 3D

1. E-commerce and retail
   • Virtual fitting/previewThe “View in Room” feature of Facebook Marketplace allows users to project 3D models of products into their own rooms to visualize size and style matches.
   • 3D Product Showcase: Merchants can quickly generate interactive 3D product images without the need for professional modeling, increasing conversion rates.
2. AR/VR and Game Development
   • Rapid Content Generation: Developers can generate 3D assets from a single photo, reducing production costs.
   • Virtual character creationSAM 3D Body: SAM 3D Body supports one-click binding of Mixamo bones to quickly generate animatable 3D characters.
3. Robotics and autonomous driving
   • environmental awareness: Provides real-time 3D environment modeling for robots to support autonomous navigation and object grasping.
   • Obstacle recognition: Understand the shape and position of surrounding objects through 3D reconstruction to enhance safety.
4. Film and animation production
   • Rapid Prototyping: The director can generate 3D scenes or character prototypes from photos to speed up pre-planning.
   • Texture and detail optimization: High-fidelity textures output from the model can be used directly in post-rendering.

How to use SAM 3D?

1. Basic Experience
   • Platform access: By Segment Anything Playground Experience online and upload photos to generate 3D models.
   • interactive operation: Rotate the model, adjust the viewing angle, zoom in and out on details, and see the effect under different lighting conditions.
2. developer integration

     • Sign up for a Meta developer account to get an API key.
     • Upload images and receive 3D model files (e.g. in GLB format) by calling the SAM 3D interface through the Edits or Vibes application.
   • local deployment::
     • Cloning GitHub open source repositories (such as the SAM 3D Objects).
     • Install dependent libraries (e.g. PyTorch 2.0+, CUDA 11.7+) and run inference scripts to generate models.
3. Advanced Features
   • Mannequin Adjustment: When using SAM 3D Body, you can control the pose or body shape in fine detail by entering 2D keypoints or segmentation masks.
   • multi-model fusion: Generate more complex virtual characters in conjunction with Meta's other tools, such as Codec Avatars.
