EasyAR Sense Unity Plugin exposes EasyAR Sense features into Unity as a plugin. It can work with or without AR Foundation. It can also work on Nreal Eyewears. See EasyAR Sense 4.4.0 release note.
EasyAR Sense Unity Plugin 4.4.0 adds many new features and improvements, highlights are,
Support Unity AR Foundation
EasyAR can now work side-by-side with AR Foundation, which powers up EasyAR and vice versa. You can take both advantages from EasyAR and AR Foundation at the same time. For example, you can now make use ARKit or ARCore features exposed by AR Foundation, like environment probes, when using EasyAR sparse spatial map to localize device in a real-world environment.
The AR Foundation support is implemented as a custom camera, taking flexibility of underlying EasyAR Sense. As a reference, you can now customize the plugin to support other AR Frameworks more easily.
Support Nreal Eyewears (VIO capable AR Eyewears)
EasyAR now supports Nreal devices. The Nreal support is implemented as a custom camera, taking flexibility of underlying EasyAR Sense.
Support Unity Universal Render Pipeline
URP support is now built in.
Support EasyAR Cloud SpatialMap
EasyAR Cloud SpatialMap provides city-scale AR cloud solution. EasyAR Sense Unit Plugin is one of the essential development tools supporting Cloud SpatialMap application development.
New Motion Fusion Feature
EasyAR motion fusion improves image and object tracking stability, and continously tracks those targets when they go out of camera scope when any type of motion tracking is available. This new feature provides a much better tracking result instead of simply running motion tracking and image tracking at the same time as what can be done in the old versions.
New AR Session creation workflow
AR session and other AR components creation now makes use of GameObject menu, which is way more flexible and convenient. Prefabs are marked as obsolete and will be removed in future releases.
Detailed changes are as bellow,
