ARBodyAnchor¶

Represents a tracked human body with skeletal joint data.

Description¶

Provides the root pose, tracking state, estimated scale factor, and optional ARBodySkeleton for a detected body. Delivered through anchor signals when using ARSession.run_body_tracking(). iOS only. On visionOS and macOS, this type exists for API consistency but is never populated with real data.

Properties¶

float	estimated_scale_factor	`1.0`
String	identifier	`""`
bool	is_tracked	`false`
ARBodySkeleton	skeleton	`null`
Transform3D	transform	`Transform3D(1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0)`

Property Descriptions¶

float estimated_scale_factor = 1.0 🔗

void set_estimated_scale_factor(value: float)
float get_estimated_scale_factor()

Estimated scale multiplier for the detected body relative to the reference skeleton.

String identifier = "" 🔗

void set_identifier(value: String)
String get_identifier()

A unique identifier for this body anchor.

bool is_tracked = false 🔗

void set_is_tracked(value: bool)
bool get_is_tracked()

Whether the body is currently tracked with reliable pose data.

ARBodySkeleton skeleton = null 🔗

void set_skeleton(value: ARBodySkeleton)
ARBodySkeleton get_skeleton()

The tracked body skeleton, if available.

Transform3D transform = Transform3D(1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0) 🔗

void set_transform(value: Transform3D)
Transform3D get_transform()

The root transform of the body in world space.
