示例1:

{
ovrTrackingState state = { 0 };
if (!session)
return state;
// Gain focus for the compositor
float time = (float)ovr_GetTimeInSeconds();
// Get the absolute tracking poses
vr::TrackedDevicePose_t* poses = session->poses;
// Convert the head pose
state.HeadPose = REV_TrackedDevicePoseToOVRPose(poses[vr::k_unTrackedDeviceIndex_Hmd], time);

}

// The calibrated origin should be the location of the seated origin relative to the absolute tracking space.
// It currently describes the location of the absolute origin relative to the seated origin, so we have to invert it.
