sam3d | 3D World Image

sam3d is Meta’s innovative single-image 3D reconstruction model that transforms ordinary photos into ready-to-use 3D assets. By integrating open-vocabulary segmentation with geometry, texture, and layout predictions, it allows users to create detailed 3D models from just one RGB image. This tool is designed for various applications, including creative tools, AR commerce, robotics perception, and scientific visualization.

1. Single-Image to 3D Conversion

   sam3d infers full 3D shape, texture, and layout from a single RGB photo, eliminating the need for multi-view and LiDAR setups in many workflows.

2. Open-Vocabulary Segmentation

   It utilizes SAM 3 prompts (text, points, boxes) to isolate objects, enabling targeted 3D asset generation from natural language or visual cues.

3. Open Ecosystem

   sam3d ships with checkpoints, inference code, and benchmarks like Artist Objects and SAM 3D Body, facilitating reproducible research and production pilots.

4. AR/VR Ready

   The model is compatible with AR/VR pipelines, allowing users to import single-image scans into virtual rooms and mixed reality scenes.

5. Efficient Inputs

   It reduces capture complexity by working with legacy photos, user-generated content, and single product shots.

6. Benchmarking Tools

   sam3d includes clear evaluation suites for teams to measure performance, identify gaps, and fine-tune their processes.

What makes sam3d different from photogrammetry?

sam3d reconstructs 3D models from a single image using SAM 3 prompts, while photogrammetry requires multiple calibrated views and controlled capture environments.

Does sam3d need depth sensors?

No, sam3d operates solely on RGB images, minimizing reliance on LiDAR or depth cameras.

Can sam3d isolate specific objects?

Yes, by using SAM 3 prompts, users can mask specific objects for clean reconstruction.

Where does sam3d struggle?

It may have difficulties with low-resolution, noisy, or heavily occluded images, as well as with rare object categories and dynamic scenes.

Is sam3d open-source?

Yes, Meta provides checkpoints, inference code, and benchmarks for reproducible research and production use.

How does sam3d help AR commerce?

It converts single product shots into AR-ready 3D assets, enabling features like "view in room" with minimal capture overhead.
