Meta Spatial SDK Samples

This repository is a collection of code samples and projects that demonstrate the capabilities of Meta Spatial SDK. Meta Spatial SDK is a new way to build immersive apps for Meta Horizon OS. Meta Spatial SDK lets you combine the rich ecosystem of Android development and the unique capabilities of Meta Quest via accessible APIs.

The samples in this repository showcase various features of the SDK, such as spatial anchors, scene understanding, and object recognition. Each sample project includes source code, build scripts, and documentation to help developers understand how to use the SDK to build their own spatially-aware applications.

Whether you're a seasoned developer or just starting out with Meta Quest/Horizon OS, the Meta Spatial SDK Samples are a valuable resource for learning how to leverage the power of spatial computing in your applications.

Requirements

To try out these sample apps, you will need:

• A Meta Quest device (Quest 2/3/3S/Pro)
  • Meta Quest build v69.0 or newer
• Mac or Windows
  • Android Studio Hedgehog or newer
  • Meta Spatial Editor

Getting Started

First, ensure that all of the requirements are met.

Then, to build and run a sample:

1. Clone this repository to your computer
2. Open the specific sample app with Android Studio
3. Plug in your Quest device to your computer
4. Click the "Run" button in the Android Studio toolbar, the app will now be running on your headset

Notes:

• All samples, except MRUKSample, require you to install Meta Spatial Editor.
• MediaPlayerSample contains an example of custom shaders, which requires the NDK to be installed and set up in app/build.gradle.kts (ex. ndkVersion = "27.0.12077973")
• CustomComponentsSample supports our custom OVRMetrics integration
  • Download & Enable OVRMetricsTool Steps

Samples

We have 10 sample apps, demonstrating various features of Meta Spatial SDK:

• AnimationsSample shows how to play animation clips, create reusable animation drivers, and demonstrates frame-based procedural animation.
• HybridSample shows how to begin with a standard Android-based 2D panel experience and switch between an immersive experience that hosts the same panel.
• CustomComponentsSample shows how to create a custom component that embodies the data shared across various instances of an application.
• MediaPlayerSample shows how to build an immersive video playback experience.
• MixedRealitySample shows an immersive experience that interacts with the user's physical surroundings.
• MrukSample shows an immersive experience influenced by the user's physical surroundings.
• Object3DSample shows inserting 3D objects into a scene and adjusting their properties in Meta Spatial Editor.
• PhysicsSample shows adding a physics component and adjusting its properties in Meta Spatial Editor.
• SpatialVideoSample shows how to play video with spatialized audio.
• StarterSample is a starter project that is part of Getting Started with Meta Spatial SDK.

We also have a starter app CustomComponentsStarter, which only contains the boilerplate code of CustomComponentsSample. You can download this starter app and follow this tutorial to build a LookAt app with Meta Spatial Editor and SDK.

Showcases

The Showcases folder contains three apps which are deployed to the Meta Horizon Store. These are fully-featured applications built with Meta Spatial SDK, and are open-sourced here in this repository.

• Focus
  • Download from the store
• Media View
  • Download from the store
• Geo Voyage
  • Download from the store

Documentation

The documentation for Meta Spatial SDK can be found here.

0.5.4 Updates

Our full update list can be found in our CHANGELOG.md file.

Added

• Added onHeadsetMounted and onHeadsetUnmounted APIs for detecting when a user puts on or takes off their headset.

Changed

• None

Deprecated

• None

Fixed

• Fixed Windows specific hot reload bug with "Read-only filesystem" error in Gradle task.
• Fixed crash where a SceneLayer was being destroyed twice due to garbage collection.

Spatial SDK Gradle Plugin

The samples all include the Spatial SDK Gradle Plugin in their build files. This plugin is used for the Spatial Editor integration and for build-related features like custom shaders.

Meta collects telemetry data from the Spatial SDK Gradle Plugin to help improve MPT Products. You can read the Supplemental Meta Platforms Technologies Privacy Policy to learn more.
