Augmented reality has now become an important part of our lives. We are already shopping for furniture, clothes and cosmetics with AR apps. AR games keep both children and adults engaged and entertained, and AR business and tech apps help professionals in various fields work more efficiently. All of these apps are built with specific development tools, called augmented reality SDKs (software development kits).
The Key Features of Popular Augmented Reality SDKs
Just like software and web development platforms, augmented reality SDKs have already undergone a selection process by professional developers. They have a set of expectations in terms of functionalities, ease of use and, of course, cost.
The main features used in the evaluation of an AR SDK are:
- License type: open source, free, or commercial
- Supported platforms: Android and iOS
- Supported smart glasses
- Unity support: one of the most powerful engines for building games and most game developers use it;
- 3D tracking
- Geolocation: an essential functionality for creating location-based apps and games
- SLAM (Simultaneous Localization and Mapping): allows an application to map environments and track its own movements in that environment
The Most Frequently Used Augmented Reality SDKs
The following list does not ennumerate the best SDKs per se. The order we used in presenting these AR SDKs does not represent a ranking, but is purely for convenience.
Vuforia is extremely popular among augmented reality app developers because it offers a wide range of functions, such as:
- Text recognition for over 100,000 words in the English vocabulary
- 2D and 3D object recognition (geometric shapes and consumer products)
- On-device and cloud recognition
- Video playback
- Virtual buttons which turn various surfaces into touch screens
The basic functions are available for free, but with the Vuforia watermark applied on each developed app. The Classic license has a one-time fee of $499, and the Cloud license costs $99 per month.
Apple has shown a huge interest in augmented reality and it is not surprising that the company wanted to make its own contribution to augmented reality SDKs. Apple ARKit is completely free and comes as a part of iOS 11+.
Some of the most important features it offers developers are:
- Stable and fast motion tracking
- SLAM tracking
- Support for Unity, Unreal and SceneKit
- Plane estimation with basic boundaries
- Scene understanding, such as placing virtual objects on vertical surfaces with the newest iOS 11.3 update, and light estimation
As a free, open-source AR SDK, Apple ARKit already has an active community of developers who contribute to make the platform more stable, efficient and useful.
Google came up with its own AR SDK when it launched Android SDK 7.0. Thus, their augmented reality app development platform is open-source and free to use, and is currently compatible with approximately 100 million devices running on Android.
The top features of this augmented reality SDK are:
- Support for Unity, Unreal, and Java/OpenGL
