```kotlin
public interface SpatialAlignment
```
An interface to calculate the position of a sized box inside of an available 3D space.
[SpatialAlignment](/jetpack-compose/androidx.xr.compose/compose/interfaces/SpatialAlignment) is often used to define the alignment of a layout inside a parent layout.
## Functions
horizontalOffset
```kotlin
public fun horizontalOffset(
width: Int,
space: Int,
layoutDirection: LayoutDirection = LayoutDirection.Ltr,
): Int
```
Provides the horizontal offset from the origin of the space to the origin of the content.
#### Parameters
| | |
| --- | --- |
| width | The content width in pixels. |
| space | The available space in pixels. |
| layoutDirection | LTR or RTL. |
verticalOffset
```kotlin
public fun verticalOffset(height: Int, space: Int): Int
```
Provides the vertical offset from the origin of the space to the origin of the content.
#### Parameters
| | |
| --- | --- |
| height | The content height in pixels. |
| space | The available space in pixels. |
depthOffset
```kotlin
public fun depthOffset(depth: Int, space: Int): Int
```
Provides the depth offset from the origin of the space to the origin of the content.
#### Parameters
| | |
| --- | --- |
| depth | The content depth in pixels. |
| space | The available space in pixels. |
position
```kotlin
public fun position(
size: IntVolumeSize,
space: IntVolumeSize,
layoutDirection: LayoutDirection = LayoutDirection.Ltr,
): Vector3
```
Provides the origin-based position of the content in the available space.
#### Parameters
| | |
| --- | --- |
| size | The content size in pixels. |
| space | The available space in pixels. |
| layoutDirection | LTR or RTL. |
