In this article, the author discusses augmented reality (AR) and Google's ARCore library, which allows developers to build AR apps on Android devices. The author uses ARCore to create a pirate-themed app that can display multiple objects, including action figures, in a virtual environment. The app extends the original ARCore demo by adding new features such as rendering different objects and layout rendering. The author provides an example of how to add custom textures and layouts to the AR scene, allowing for more flexibility in creating AR content. The article concludes with a call to action to explore the ARCore guide from Google Developers and build own AR apps.
