EasyAR Sense Unity Plugin is a very thin wrapper build above EasyAR Sense C# API to expose EasyAR Sense features into Unity. See EasyAR Sense 4.0.0 release note.

EasyAR has a big family now, starting from version 4, the previously known EasyAR SDK will be named EasyAR Sense, providing sensing abilities of the real world. All 3.0 features are available in this version.

EasyAR Sense is a standalone SDK, it provides flexible dataflow-oriented component-based API and do not depend on any non-system libraries or tools like Unity3D.

As for the Unity support, EasyAR Sense Unity Plugin, is a very thin wrapper to expose EasyAR Sense features into Unity. All code of EasyAR Sense Unity Plugin is open sourced with well-designed interface. You can use the plugin directly to create AR experience within short time. You can also reference the source code to create more custom usages of EasyAR Sense or even a Unity Plugin of your own.

EasyAR Sense Unity Plugin has gained great improvements, highlights are,

  1. Consistent design evolution

    All features and best parts from Unity Plugin for EasyAR Sense 1/2/3 are kept in this version. The plugin now use as much Unity features as possible, like start/stop in OnEnable/OnDisable, most EasyAR Sense features can work without writing scripts. All new features of EasyAR Sense 4.0 are supported and bugs are fixed.

  2. Editor experience improvements

    Gizmos are used to show image targets in editor to replace auto generated mesh in old versions with better experience. Critical errors like license key validation failures are shown on screen with a popup to help debug. Image target data generation is also provided as a Unity tools window instead of just APIs.

  3. More samples and cover more detailed APIs

    All new features and combination of different algorithms are demonstrated. Eyewear support has samples, with pre-calibrated parameters of ShadowCreator Action One and EPSON BT-350. Answers to many how to use questions from community are available in these samples. Thank you for your feedbacks!

EasyAR Sense 4.0 provides you with three subscription modes: Personal Edition (Free), Professional Edition (Monthly Payment) and Enterprise Edition (Customized).
