Place overlays on a camera preview and adjust their position depending on device attitude.

Take a look at sample project TGLAugmentedRealityExample.xcodeproj.

Via CocoaPods:

• Add pod 'TGLAugmentedRealityView', '~> 1.0' to your project's Podfile

Or the "classic" way:

• Add files in folder TGLAugmentedRealityView to your project

Then in your project:

• Implement TGLARViewDataSource and TGLARViewDelegate protocols
• Place a TGLARView in your storyboard and set its -dataSource and -delegate outlets

Optionally:

• Implement TGLARCompass protocol
• Set TGLARView's -compass outlet

Build and run TGLAugmentedRealityExample.xcodeproj on an iDevice. The app will run on the simulator, too, but will give you no camera image or device orientation.

Tap the blue button and search for POIs in the map view. When finished, close the map to reveal the AR view. The POIs will be displayed with a callout and a billboard image.

On the AR view use a horizontal pan gesture to adjust the compass heading and a pinch gesture to adjust the zoom factor, if available in the active video format.

• ARC
• iOS >= 9.3
• Xcode 9
