EasyAR 1.3.0 has a few new features and some improvements. Major highlights are,

1) Multi-target support.

EasyAR now allows you to track multiple targets simultaneously. You can use one tracker to do that, or use multiple trackers when targets are loaded into different trackers. And you can change the maximum number of simultaneous tracked target at runtime. Please reference this for more detailed descriptions.

2) Interface changes for more flexible use.

We have adjusted a few interfaces while the basic framework stays unchanged, and for Unity, added more prefabs to show how to use EasyAR prefabs like building blocks. This article shows how to migrate your apps from EasyAR 1.0~1.2 to the new 1.3 version.

3) Detection and tracking optimization, reduce shakiness.

4) Performance optimization and power reduction.

Detailed changes are as bellow,

+ added multi-target support

+ added a few samples to show typical multi-target usages

+ added a sample to do tracking and read QR code simultaneously

+ added interface to explicitly flip camera input horizontally

+ added interface to disable automatic Android rotation detection

+ added interface to set rotation externally

+ Unity: optimized rendering performance

+ Unity: added many prefabs to show how to combine basic prefabs

+ Unity: added EasyARBehaviour for input key and initialize, and use explicit pause/resume/quit handlers

+ Unity: added an option to show/hide RealityPlane
