FacioEngine was the SDK from FacioMetrics LLC. This SDK was written in C++ and was capable of facial feature detection along with emotion detection and facial attributes detection in realtime. The facial feature detection was both performed in 2D and 3D.
This SDK was available for Desktop (Linux, MacOs and Windows) and Mobile (Android and iOS) platforms. For this reason, different basic apps were created to showcase the different capabilities of each software.
