With Jetpack Compose for XR, you can use spatialized components like [rows](https://developer.android.com/reference/kotlin/androidx/xr/compose/subspace/SpatialRow.composable.md.txt) and [columns](https://developer.android.com/reference/kotlin/androidx/xr/compose/subspace/SpatialColumn.composable.md.txt) to build spatial UI and layouts using a [familiar, declarative Compose model](https://developer.android.com/develop/ui/compose/layouts/basics). This lets you [extend your existing Android UI into 3D space](https://developer.android.com/develop/xr/jetpack-xr-sdk/add-xr-to-existing) or build entirely new immersive 3D apps. This library also provides [subspace composeables](https://developer.android.com/reference/kotlin/androidx/xr/compose/subspace/SubspaceComposable.md.txt), such as [spatial panels](https://developer.android.com/reference/kotlin/androidx/xr/compose/subspace/SpatialPanel.composable) and [orbiters](https://developer.android.com/reference/kotlin/androidx/xr/compose/spatial/Orbiter.composable.md.txt), which let you place your existing 2D Compose or Views-based UI in a spatial layout. Other subspace composeables handle other types of spatial use cases, such as [`SceneCoreEntity`](https://developer.android.com/reference/kotlin/androidx/xr/compose/subspace/SceneCoreEntity.composable.md.txt) that lets you [place entities](https://developer.android.com/develop/xr/jetpack-xr-sdk/ui-compose#use-scenecoreentity) like 3D models relative to your UI. ![Develop UI XR components orbiter generic example](https://developer.android.com/static/images/develop/xr/jetpack-xr-sdk/index/develop-ui-xr-component-orbiter-generic.jpg) ## Guides This section includes the following developer guides: ### Layout components - [Overview](https://developer.android.com/develop/xr/jetpack-xr-sdk/compose/components.md.txt) - [Orbiter](https://developer.android.com/develop/xr/jetpack-xr-sdk/compose/orbiter.md.txt) - [SceneCore entity](https://developer.android.com/develop/xr/jetpack-xr-sdk/compose/scene-core-entity.md.txt) - [Spatial dialog](https://developer.android.com/develop/xr/jetpack-xr-sdk/compose/spatial-dialog.md.txt) - [Spatial external surface](https://developer.android.com/develop/xr/jetpack-xr-sdk/compose/spatial-external-surface.md.txt) - [Spatial gLTF model](https://developer.android.com/develop/xr/jetpack-xr-sdk/compose/spatial-gltf-model) - [Spatial panel](https://developer.android.com/develop/xr/jetpack-xr-sdk/compose/spatial-panel.md.txt) ### Material Design for spatial UI - [Implement Material Design for XR](https://developer.android.com/develop/xr/jetpack-xr-sdk/material-design.md.txt) ### Working with existing Views-based layouts - [Build spatial UI for existing Android Views-based apps](https://developer.android.com/develop/xr/jetpack-xr-sdk/develop-ui-views)
