The Ultimate Guide to Downloading and Using AR Foundation for Augmented Reality Development


How to Download AR Foundation




Augmented reality (AR) is a technology that enhances the real world with digital content, such as images, videos, sounds, or 3D models. AR can create immersive and interactive experiences that can be used for entertainment, education, business, and more.

But how can you create your own AR apps? One of the easiest and most powerful ways is to use Unity, a popular game engine and development platform that supports multiple platforms and devices. And within Unity, you can use AR Foundation, a framework that allows you to build cross-platform AR apps with a unified workflow.


What is AR Foundation and why use it?




AR Foundation is an official Unity package that provides an interface for developing AR apps that can run on different devices, such as Android, iOS, Magic Leap, or HoloLens. It does not implement any AR features itself, but rather relies on separate plugin packages that provide platform-specific implementations.


The main advantage of using AR Foundation is that you can write your AR logic once and then deploy it to multiple platforms without making any additional changes. This saves you time and effort and ensures consistency across your app. You can also take advantage of features that are not yet available on some platforms by using hooks that are ready to go when they are enabled.


What are the benefits of AR Foundation?




Some of the benefits of using AR Foundation are:



  • It supports core features from different platforms, such as device tracking, plane detection, point clouds, anchors, light estimation, environment probes, face tracking, image tracking, object tracking, meshing, body tracking, collaborative participants, human segmentation, raycasting, pass-through video, session management, and occlusion.



  • It integrates with other Unity features and workflows, such as the Universal Render Pipeline (URP), the Entity Component System (ECS), or the XR Interaction Toolkit.



  • It enables you to create rich and diverse AR experiences with your existing Unity skills and assets.



  • It is compatible with Unity MARS (Mixed and Augmented Reality Studio), a tool that allows you to build intelligent AR apps that interact with the real world.
