## API Reference

> Source set: Android

```kotlin
public fun interface OrbiterPoseProvider
```

Calculates the `Pose` of an [Orbiter](/jetpack-compose/androidx.xr.compose/compose/composable-functions/Orbiter) in 3D space relative to its spatial parent.

## Functions

### calculatePose

```kotlin
public fun calculatePose(
        anchorSize: IntSize,
        layoutDirection: LayoutDirection,
        orbiterContentSize: IntSize,
    ): Pose
```
