ARCore is a platform developed by Google that allows developers to create augmented reality (AR) experiences for Android devices. It provides the necessary tools, libraries, APIs, and ARCore SDK to enable the detection of the physical environment and the placement of virtual objects in real time.
ARCore utilizes various technologies to create AR experiences. These include:
Motion Tracking: ARCore tracks the device’s position and orientation in real-time, allowing virtual objects to be placed accurately within the user’s environment. It uses the device’s camera and sensors to detect and track feature points in the environment, such as edges and corners of objects.
Environmental Understanding: ARCore analyzes the physical environment by mapping the surrounding surfaces, such as floors, walls, and tabletops. This helps virtual objects interact realistically with the real world and allows for occlusion, where virtual objects can be hidden behind physical objects.
Light Estimation: ARCore estimates the lighting conditions in the environment, allowing virtual objects to be illuminated realistically. This ensures that virtual objects appear to be a part of the physical world, matching the lighting and shadows of the surroundings.
Anchors: ARCore allows developers to create anchors, which are specific points in the physical environment where virtual objects can be placed and persist over time. Anchors help maintain the spatial relationship between the virtual and real objects, even as the user moves or interacts with the scene.
Augmented Images: ARCore supports the detection and tracking of pre-defined images in the environment. This enables developers to trigger AR experiences based on specific images, such as posters, logos, or product packaging.
Most Recent ARCore Features
Google ARCore has been continuously evolving, and several recent features have been added to enhance the capabilities of the platform. Here are some of the most recent features:
Depth API: ARCore now includes a Depth API, allowing developers to access depth information from the device’s camera. This enables more realistic occlusion and physics-based interactions between virtual and real objects, making AR experiences more immersive and interactive.
Augmented Faces: ARCore introduced support for Augmented Faces, enabling developers to create AR experiences that track and overlay virtual content onto the user’s face. This feature opens up opportunities for creative face filters, personalized avatars, and facial expression tracking in AR applications.

Light Estimation API Enhancements: The Light Estimation API has been enhanced to provide more accurate and detailed information about the lighting conditions in the environment. This allows developers to create more realistic and visually appealing AR experiences by adjusting the lighting of virtual objects to match the real-world surroundings accurately.
Augmented Images Enhancements: The Augmented Images feature has been improved to provide better image detection and tracking capabilities. Developers can now detect and track multiple images simultaneously, making it possible to create more complex and interactive AR experiences based on specific images in the environment.
Cloud Anchors: ARCore introduced Cloud Anchors, which allow shared AR experiences across multiple devices. This feature enables users to collaboratively interact with the same virtual objects and scenes, fostering social and multiplayer AR applications.
Instant Placement: With Instant Placement, ARCore can quickly and accurately place virtual objects in the physical world without requiring a surface detection step. This simplifies the user experience and allows for a more seamless integration of virtual objects into the environment.
Raw Depth API: Recently, Google released an experimental Raw Depth API for ARCore, providing developers with access to raw depth data from supported devices’ depth sensors. This allows for a more precise depth understanding and opens up possibilities for advanced AR applications, such as improved occlusion and 3D reconstruction.
Game Engine Integration with ARCore
ARCore, developed by Google, offers seamless integration with popular game engines, allowing developers to incorporate augmented reality (AR) experiences into their games. By leveraging ARCore’s capabilities within game engines, developers can create immersive and interactive AR gameplay. Here are some notable integrations of ARCore with game engines:
Unity: ARCore provides native support for Unity, one of the leading game engines in the industry. Unity’s AR Foundation package allows developers to build AR experiences using ARCore, making it easy to create cross-platform AR games for Android devices.
The integration provides access to ARCore’s features, such as motion tracking, environmental understanding, and light estimation, within the Unity editor.
Unreal Engine: ARCore also integrates with Unreal Engine, a powerful and widely used game engine. Developers can utilize the ARCore plugin for Unreal Engine to build AR experiences with advanced graphics and physics capabilities.
The integration enables seamless access to ARCore’s features, including motion tracking and environmental understanding, empowering developers to create high-quality AR games.
Godot: The open-source game engine Godot also offers support for ARCore through community-driven plugins. Developers can leverage these plugins to incorporate ARCore features into their Godot projects and create AR games for Android devices.
The integration allows for motion tracking, environmental understanding, and other ARCore functionalities within the Godot game engine.
