## What it is
Google's ARCore SDK for Unity, providing native APIs for augmented reality features such as motion tracking, environmental understanding, and light estimation. It is deprecated and only intended for maintaining legacy Unity projects that cannot migrate to AR Foundation.

## Use cases
- build augmented reality apps in unity
- add motion tracking to a mobile ar app
- detect surfaces and planes for ar placement
- estimate lighting in ar scenes
- maintain a legacy unity arcore project

## When to choose
- you are maintaining an existing Unity project already built on this SDK
- you cannot migrate to Unity AR Foundation

## When to avoid
- you are starting a new Unity AR project (use ARCore Extensions for AR Foundation)
- you target Unity 2020 or later
- you need actively maintained AR tooling

## Facets
- artifact type: library

- function: sdk, graphics, simulation
- domain: mobile-development, cross-platform
