Lately I have been working on trying facial recognition with the Kinect, using the new Developer Toolkit (v1.5.1). The API for the FaceTracking tools can be found here: http://m
The picture you attached refers to the 2D model. GetProjected3DShape has nothing to do with the picture.
Use IFTResult.Get2DShapePoints to get 2D face points. If you are using the FaceTrackingBasics-WPF example, you have to write a C# wrapper for that method.
