## Question

First, i used kinect sdk, c# language to develop kinect skeleton. then i found joint angls using the "AngleBetweenTwoVectors" function

public double AngleBetweenTwoVectors(Vector3D vectorA, Vector3D vectorB) { double dotProduct = 0.0; vectorA.Normalize(); vectorB.Normalize(); dotProduct = Vector3D.DotProduct(vectorA, vectorB); return (double)Math.Acos(dotProduct) / Math.PI * 180; }Now i want to calculate some specific rotational angles like shoulder pitch rotation(rotation around y axis) using kinect sdk & c# language. Does anyone know how to calculate it?
