EasyAR Sense Release Notes
EasyAR is a flexible and easy-to-use augmented reality engine.
EasyAR Sense provides the capability to perceive the real world, supporting plane image tracking, 3D object tracking, surface tracking, motion tracking, sparse spatial map, dense spatial map, and Mega.
EasyAR Sense is a standalone SDK that does not rely on non-system components or tools like Unity3D, offering flexible dataflow-based componentized APIs.
EasyAR Sense 4.0 offers four subscription models: free personal edition, monthly-paid professional edition, one-time-paid classic edition, and customized-feature enterprise edition.
