SAM 3D Body Generator

WaveSpeedAI SAM 3D Body Image-to-3D

SAM 3D Body (wavespeed-ai/sam-3d-body) generates a 3D human body asset from a single input image, with an optional mask to isolate the body region. It’s designed for practical pipelines where you want fast, repeatable 3D body reconstruction from photos and screenshots.

You provide the source image (and optionally a mask image). The API returns output URL(s) for the generated 3D result.

Key capabilities

• Single-image 3D human body generation from an input image URL.
• Optional mask-guided subject isolation via mask_image for cleaner results when the background is busy.
• Simple, minimal input surface (just image, plus optional mask_image)—easy to plug into automation.
• Asynchronous job workflow with task status (created / processing / completed / failed) and output URLs when finished.
• Production-style response payloads including timing info and NSFW flags in the result metadata.

Parameters and how to use

• image: (required) Input image URL for 3D body generation.
• mask_image: Optional mask image URL to constrain processing to a specific region (typically the body).

Prompt

This model is image-conditioned and does not accept a text prompt. Your “instruction” is primarily the image content (and optional mask_image).

Media (Images)

Input

• image must be a publicly accessible URL when calling the REST API.
• For best results, use a clear full-body subject (minimal occlusion, good lighting, sharp edges).
• Avoid heavy motion blur, extreme fisheye distortion, or large cut-offs (missing limbs / cropped torso).

Optional mask

• mask_image should match the same framing and dimensions as image.

• Use the mask when:

  • the background is cluttered,
  • multiple people appear,
  • the body boundary is ambiguous (similar colors, low contrast).

Other parameters

mask_image

• When to use: Improve subject isolation and reduce background leakage into the reconstruction.
• What to send: A mask image URL aligned to image (commonly a binary or high-contrast foreground mask).

After you finish configuring the parameters, click Run, preview the result, and iterate if needed.

Notes

• Best input = best 3D. A well-lit, centered, full-body image will generally outperform a busy, low-contrast scene.
• Use mask_image as a control knob. If the output includes background artifacts or misses body parts, add a mask and re-run.
• Expect iteration for hard cases. Complex poses, heavy occlusions (arms crossing torso), and multiple overlapping people often need a cleaner source image or a tighter mask.
