About Sam 3 · 3D Body
Builds 3D body meshes of the people in one image. People are detected automatically, or you can pass a binary mask in `mask_url` (white for person). Toggles control per-person .ply export, 3D keypoint markers in the GLB, and the full MHR parameter set in the metadata. Returns a GLB, meshes, metadata and a visualization image.
Parameters
Send either the canonical name or the native name, not both. Canonical names
image_urlrequired
image
mask_urloptional
mask
export_meshesoptional
include_3d_keypointsoptional
include_mhr_paramsoptional
File parameters take a public https:// URL, a data: URI up to 10 MB, or the file_url of an upload. Files
