Simple intel realsense app to track face position

I'd like a complete C# or C++ project delivered that will track face positions. A dll that spins up a thread that starts tracking faces. I can call that will return an x/y/z of the face in relation to the camera. And a simple console test app that just constantly outputs xyz position while a face is being tracked. Needs to work with the intel realsense sdk and use depth data to get the face position. Detection should proly be rgb. Can be opencv, openvino, dnn. Lemme know if you want to use something else and that's probably okay too. directions: x+ = right y+ = up z+ = forward dll exports: void StartTracking() - creates a thread, opens the camera and starts tracking bool GetTrackedFace(float *x, float *y, float *z) - returns false if no face available, true if there is a face. Also the position of the face in x/y/z. void StopTracking() - ends the thread and cleans up. What I need is; dll exports: void StartTracking() - creates a thread, opens the camera and starts tracking bool GetTrackedFace(float *x, float *y, float *z) - returns false if no face available, true if there is a face. Also the position of the face in x/y/z. void StopTracking() - ends the thread and cleans up. test app: console application, calls the dll, streams position of tracked face when there is one. nothing when there isn't.
