Recording and Playback

With the Recording and Playback APIs, you can record video and AR data once within a given environment and use that content to replace a live camera session for testing purposes. ARCore saves recorded sessions to MP4 files that contain multiple video tracks and other miscellaneous data on the device. You can then point your app to use this data in place of a live camera session. This allows you to replay that content indefinitely to try out different AR effects without having to return to the field.

What's new in ARCore v1.19.0

This release adds the following notable changes:

• New Instant Placement API for Android , Android NDK , and Unity .
• New guidance for building for Android 11 with Unity.

Instant Placement

The Instant Placement API allows the user to place an AR object on the screen without having to wait for ARCore to detect surface geometry. Object placement is refined in real time as the user moves further around the environment. Once ARCore detects the correct pose in the region where the AR object is placed, the white object automatically updates to be pose-accurate, and becomes opaque.

The following clip shows a virtual Android figure on a real-world table. The figure is white and much smaller when first placed. After ARCore refines its calculations of the scene dimensions, the figure jumps to a more accurate position. This may result in a difference in the perceived "size" of the object.

What's new in ARCore v1.18.0

This release adds the following notable changes:

• New Depth API for Android , Android NDK , and Unity .
• New guidance for creating Augmented Faces assets and importing them into Android Studio.
• Depth API will be supported in 4.1.0-preview.2 for both AR Foundation and ARCore XR Plugin .

Depth API

On depth-supported devices , the Depth API uses the ARCore-supported device's RGB camera, or active depth sensor if available, to create depth maps. You can then use the per-pixel depth provided by a depth map to make virtual objects accurately appear in front of or behind real world objects, enabling immersive and realistic user experiences.

For example, the following images show a virtual Android figure in a real space containing a trunk beside a door. The Depth API properly occludes the figure behind the edge of the trunk.

• C: ArEarth_getGeospatialPose()
• iOS: GARGeospatialTransform.eastUpSouthQTarget
• Unity: GeospatialPose.EunRotation()

Geospatial pose conversions

Geospatial poses can now be converted to and from world-space (AR) poses.

To get the Geospatial pose from an AR pose:

• Java/Kotlin: Earth.getGeospatialPose()
• C: ArEarth_getGeospatialPose()
• iOS: GARSession.geospatialTransformFromTransform:error:
• Unity: AREarthManager.Convert(Pose)

To get the AR pose from a Geospatial pose:

• Java/Kotlin: Earth.getPose()
• C: ArEarth_getPose()
• iOS: GARSession.transformFromGeospatialCoordinate:altitude:eastUpSouthQTarget:error:
• Unity: AREarthManager.Convert(GeospatialPose)

Geospatial poses obtained from these functions have a heading value set to zero. Instead, use the following:

• Android (Java/Kotlin/C): The pose's EUS quaternion
• iOS: The pose's eastUpSouthQTarget
• Unity: The pose's EunRotation

What's new in ARCore v1.33.0

New Cloud Anchors endpoint

• To use Cloud Anchors, you must now enable the ARCore API instead of the older ARCore Cloud Anchor API , which is now deprecated. To support older app versions, you may enable both while making the transition. Apps built with ARCore SDK 1.32.0 and lower will target the older API, while apps built with ARCore SDK 1.33.0 and higher will target the new API. Note the following:
  • The new API uses the domain name arcore.googleapis.com instead of arcorecloudanchor.googleapis.com .
  • If you are using an API Key which is restricted by API, you must allow the ARCore API.
  • If you send requests to the ARCore Cloud Anchor Management API from your backend, you must also change the domain name to arcore.googleapis.com , after enabling the ARCore API.
  • The old API/endpoint will continue to be supported through August 2023.
  • See ARCore 1.33 Cloud Anchor endpoint changes for more details.

What's new in ARCore v1.24.0

This release adds the following notable changes:

• A new Raw Depth API that provides a depth image without image-space filtering
• Custom data track recording capability to the Recording & Playback API
• The ability to conduct Depth hit-tests

Raw Depth

The Raw Depth API provides depth data for a camera image that has higher accuracy than full Depth API data, but does not always cover every pixel. Raw depth images, along with their matching confidence images, can also be further processed, allowing apps to use only the depth data that has sufficient accuracy for their individual use case.

Developer guides:

• Android (Java/Kotlin)
• Android NDK (C)
• ARCore Extensions for AR Foundation
• ARCore SDK for Unity

Custom track recording

The new custom data track capability in the Recording & Playback API allows you to add custom data to an ARCore frame during recording and retrieve that same data from the frame during playback.

Developer guides:

• Android (Java/Kotlin)
• Android NDK (C)
• ARCore Extensions for AR Foundation
• ARCore SDK for Unity

Depth hit-tests

Previously, hit-tests could only be conducted on detected planes, limiting locations to large, flat surfaces. Depth hit-tests take advantage of both smooth and raw depth information to provide more accurate hit results, even on non-planar and low-texture surfaces.

Developer guides:

• Android (Java/Kotlin)
• Android NDK (C)

What's new in ARCore v1.21.0

This release adds new Recording and Playback APIs for Android , Android NDK , and Unity .

Recording and Playback

With the Recording and Playback APIs, you can record video and AR data once within a given environment and use that content to replace a live camera session for testing purposes. ARCore saves recorded sessions to MP4 files that contain multiple video tracks and other miscellaneous data on the device. You can then point your app to use this data in place of a live camera session. This allows you to replay that content indefinitely to try out different AR effects without having to return to the field.

What's new in ARCore v1.19.0

This release adds the following notable changes:

• New Instant Placement API for Android , Android NDK , and Unity .
• New guidance for building for Android 11 with Unity.

Instant Placement

The Instant Placement API allows the user to place an AR object on the screen without having to wait for ARCore to detect surface geometry. Object placement is refined in real time as the user moves further around the environment. Once ARCore detects the correct pose in the region where the AR object is placed, the white object automatically updates to be pose-accurate, and becomes opaque.

The following clip shows a virtual Android figure on a real-world table. The figure is white and much smaller when first placed. After ARCore refines its calculations of the scene dimensions, the figure jumps to a more accurate position. This may result in a difference in the perceived "size" of the object.

What's new in ARCore v1.18.0

This release adds the following notable changes:

• New Depth API for Android , Android NDK , and Unity .
• New guidance for creating Augmented Faces assets and importing them into Android Studio.
• Depth API will be supported in 4.1.0-preview.2 for both AR Foundation and ARCore XR Plugin .

Depth API

On depth-supported devices , the Depth API uses the ARCore-supported device's RGB camera, or active depth sensor if available, to create depth maps. You can then use the per-pixel depth provided by a depth map to make virtual objects accurately appear in front of or behind real world objects, enabling immersive and realistic user experiences.

For example, the following images show a virtual Android figure in a real space containing a trunk beside a door. The Depth API properly occludes the figure behind the edge of the trunk.

What's new in ARCore v1.34.0

Check if Geospatial capabilities are available in the device's current location

The Geospatial API can now check for Visual Positioning System (VPS) availability at a specified horizontal position at runtime. This API can be used without an active AR session: for example, to present an "Enter AR" button only when VPS is available.

• Java/Kotlin: Session.checkVpsAvailabilityAsync()
• C: ArSession_checkVpsAvailabilityAsync()
• iOS: GARSession.checkVPSAvailabilityAtCoordinate:completionHandler:
• Unity (AR Foundation): AREarthManager.CheckVpsAvailability()

Geospatial pose orientation

Geospatial poses now expose their orientation in 3D space.

• Java/Kotlin: feedbackGeospatialPose.getEastUpSouthQuaternion()
• C: ArEarth_getGeospatialPose()
• iOS: GARGeospatialTransform.eastUpSouthQTarget
• Unity: GeospatialPose.EunRotation()

Geospatial pose conversions

Geospatial poses can now be converted to and from world-space (AR) poses.

To get the Geospatial pose from an AR pose:

• Java/Kotlin: Earth.getGeospatialPose()
• C: ArEarth_getGeospatialPose()
• iOS: GARSession.geospatialTransformFromTransform:error:
• Unity: AREarthManager.Convert(Pose)

To get the AR pose from a Geospatial pose:

• Java/Kotlin: Earth.getPose()
• C: ArEarth_getPose()
• iOS: GARSession.transformFromGeospatialCoordinate:altitude:eastUpSouthQTarget:error:
• Unity: AREarthManager.Convert(GeospatialPose)

Geospatial poses obtained from these functions have a heading value set to zero. Instead, use the following:

• Android (Java/Kotlin/C): The pose's EUS quaternion
• iOS: The pose's eastUpSouthQTarget
• Unity: The pose's EunRotation

What's new in ARCore v1.33.0

New Cloud Anchors endpoint

• To use Cloud Anchors, you must now enable the ARCore API instead of the older ARCore Cloud Anchor API , which is now deprecated. To support older app versions, you may enable both while making the transition. Apps built with ARCore SDK 1.32.0 and lower will target the older API, while apps built with ARCore SDK 1.33.0 and higher will target the new API. Note the following:
  • The new API uses the domain name arcore.googleapis.com instead of arcorecloudanchor.googleapis.com .
  • If you are using an API Key which is restricted by API, you must allow the ARCore API.
  • If you send requests to the ARCore Cloud Anchor Management API from your backend, you must also change the domain name to arcore.googleapis.com , after enabling the ARCore API.
  • The old API/endpoint will continue to be supported through August 2023.
  • See ARCore 1.33 Cloud Anchor endpoint changes for more details.

Terrain anchors

• The Geospatial Terrain anchor API creates an anchor at a specified horizontal position and altitude relative to the horizontal position's terrain.

Android and Unity (AR Foundation) for Android

• ARCore's targetSdkVersion has been updated to Android API level 32. If your app does not specify a targetSdkVersion , your app's targetSdkVersion will become 32 due to manifest merging .
  • Android SDK: Specifying a targetSdkVersion in your project's build.gradle or AndroidManifest.xml will override ARCore's targetSdkVersion value.
  • AR Foundation for Android: Specifying a Target API Level in your Unity project's Project Settings > Player > Android > Other Settings will override ARCore's targetSdkVersion value.

What's new in ARCore v1.31.0

ARCore Geospatial API

The new ARCore Geospatial API utilizes data from Google Earth 3D models and Street View image data from Google Maps to enable your app for immersive, global-scale, location-based augmented reality experiences.

See the Introduction to the ARCore Geospatial API for platform-specific developer documentation, and to get started with the new Geospatial API.

Long-range depth

The ARCore Depth API is now optimized to include longer-range depth sensing, increasing the range of representable depth observations. All 16-bits of the depth image are used, providing a maximum range of 65535 millimeters. Previously only 13-bits were populated, with a limit of 8191 millimeters.

See the Changes to Depth for platform-specific developer documentation, and to understand the changes to the Depth API.

What's new in ARCore v1.24.0

This release adds the following notable changes:

• A new Raw Depth API that provides a depth image without image-space filtering
• Custom data track recording capability to the Recording & Playback API
• The ability to conduct Depth hit-tests

Raw Depth

The Raw Depth API provides depth data for a camera image that has higher accuracy than full Depth API data, but does not always cover every pixel. Raw depth images, along with their matching confidence images, can also be further processed, allowing apps to use only the depth data that has sufficient accuracy for their individual use case.

Developer guides:

• Android (Java/Kotlin)
• Android NDK (C)
• ARCore Extensions for AR Foundation
• ARCore SDK for Unity

Custom track recording

The new custom data track capability in the Recording & Playback API allows you to add custom data to an ARCore frame during recording and retrieve that same data from the frame during playback.

Developer guides:

• Android (Java/Kotlin)
• Android NDK (C)
• ARCore Extensions for AR Foundation
• ARCore SDK for Unity

Depth hit-tests

Previously, hit-tests could only be conducted on detected planes, limiting locations to large, flat surfaces. Depth hit-tests take advantage of both smooth and raw depth information to provide more accurate hit results, even on non-planar and low-texture surfaces.

Developer guides:

• Android (Java/Kotlin)
• Android NDK (C)

What's new in ARCore v1.21.0

This release adds new Recording and Playback APIs for Android , Android NDK , and Unity .

Recording and Playback

With the Recording and Playback APIs, you can record video and AR data once within a given environment and use that content to replace a live camera session for testing purposes. ARCore saves recorded sessions to MP4 files that contain multiple video tracks and other miscellaneous data on the device. You can then point your app to use this data in place of a live camera session. This allows you to replay that content indefinitely to try out different AR effects without having to return to the field.

What's new in ARCore v1.19.0

This release adds the following notable changes:

• New Instant Placement API for Android , Android NDK , and Unity .
• New guidance for building for Android 11 with Unity.

Instant Placement

The Instant Placement API allows the user to place an AR object on the screen without having to wait for ARCore to detect surface geometry. Object placement is refined in real time as the user moves further around the environment. Once ARCore detects the correct pose in the region where the AR object is placed, the white object automatically updates to be pose-accurate, and becomes opaque.

The following clip shows a virtual Android figure on a real-world table. The figure is white and much smaller when first placed. After ARCore refines its calculations of the scene dimensions, the figure jumps to a more accurate position. This may result in a difference in the perceived "size" of the object.

What's new in ARCore v1.18.0

This release adds the following notable changes:

• New Depth API for Android , Android NDK , and Unity .
• New guidance for creating Augmented Faces assets and importing them into Android Studio.
• Depth API will be supported in 4.1.0-preview.2 for both AR Foundation and ARCore XR Plugin .

Depth API

On depth-supported devices , the Depth API uses the ARCore-supported device's RGB camera, or active depth sensor if available, to create depth maps. You can then use the per-pixel depth provided by a depth map to make virtual objects accurately appear in front of or behind real world objects, enabling immersive and realistic user experiences.

For example, the following images show a virtual Android figure in a real space containing a trunk beside a door. The Depth API properly occludes the figure behind the edge of the trunk.

  • ARCore now tracks moving Augmented Images . Examples of moving images might be an advertisement on a passing bus or an image on a flat object held by a user as they move it around.

  • After an image has been detected, ARCore is able to continue tracking the image's position and orientation, even if the image has temporarily moved out of the camera view.

  • The new AugmentedImage.GetTrackingMethod() API enables your app to determine whether the Augmented image is currently being tracked by the camera ( FullTracking ), or is being tracked based on its last known position ( LastKnownPose ).

• Cloud Anchors documentation now includes a more detailed explanation of how anchors are hosted and resolved .
