how to get the head roration parameter?
So I would like to make a camera rotate as rift users rotate their head. I think there is a build-in parameter that I could directly get from rift. Could somebody instruct me on how to do so?

- Yes, it shows this in the documentation. Here are the relevant lines (in C++):
frameTiming = ovrHmd_BeginFrameTiming(hmd, 0);
ovrTrackingState ts = ovrHmd_GetTrackingState(hmd, frameTiming.ScanoutMidpointSeconds);
if (ts.StatusFlags & (ovrStatus_OrientationTracked | ovrStatus_PositionTracked)) {
Posef pose = ts.HeadPose.ThePose;
float yaw, pitch, roll;
pose.Rotation.GetEulerAngles<Axis_Y, Axis_X, Axis_Z>(&yaw, &pitch, &roll);

Thank you! but I mean I am really new to oculus rift development. After I plug in oculus rift and set it up, I can just write a C++ program to fetch these parameters right?
