An object that represents a body pose joint in 3D space.

```
struct Joint3D
```

## Topics

### Creating a joint

[`init(position: simd_float4x4, localPosition: simd_float4x4, identifer: String, parentJoint: String)`](/documentation/Vision/Joint3D/init(position:localPosition:identifer:parentJoint:))

Creates a 3D joint.

### Inspecting a joint

[`let localPosition: simd_float4x4`](/documentation/Vision/Joint3D/localPosition)

The joint position relative to the parent joint.

[`let position: simd_float4x4`](/documentation/Vision/Joint3D/position)

The joint position relative to the camera.

[`let parentJoint: String`](/documentation/Vision/Joint3D/parentJoint)

The parent joint in the observation.

[`let identifier: String`](/documentation/Vision/Joint3D/identifier)
