Reading Sensor data with GLM and OpenGL ...

Thanks for the help. I guess my main problem is really theoretical; I am not exactly sure how to alter my working code for basic walk throughs to incorporate the rift,

Here is my working code that DOESN'T use the rift.

I want to maintain the control that a person has with the mouse against the camera so I am not sure how to incorporate the Rift's sensor data against that.

The CurrentCameraViewingSettings.Yaw and Pitch values are altered when the mouse is moved by the user and then slowly drops to zero.

I'd love to incorporate the position data as well.

I guess Math isn't my strong suite...

void GlMaintenance::FastUpdateCamera() {
	DirectionOfWhereCameraIsFacing = glm::normalize(CenterOfWhatIsBeingLookedAt - PositionOfEyesOfPerson);
	switch (CurrentCameraMode) {
	case (ModeOfCamera::ORTHOGONAL) :
		break;
		Projection = glm::ortho(CurrentOrthoParameters.LeftPlane, CurrentOrthoParameters.RightPlane,
			CurrentOrthoParameters.BottomPlane, CurrentOrthoParameters.TopPlane);
	case (ModeOfCamera::PERSPECTIVE) :
	default:
		CameraAxis = glm::cross(DirectionOfWhereCameraIsFacing, DirectionOfUpForPerson);
		CameraQuatPitch = glm::angleAxis(CurrentCameraViewingSettings.Pitch, CameraAxis);
		CameraQuatYaw = glm::angleAxis(CurrentCameraViewingSettings.Yaw, DirectionOfUpForPerson);
		CameraQuatRoll = glm::angleAxis(CurrentCameraViewingSettings.Roll, CameraAxis);
		CameraQuatBothPitchAndYaw = glm::cross(CameraQuatPitch, CameraQuatYaw);
		CameraQuatBothPitchAndYaw = glm::normalize(CameraQuatBothPitchAndYaw);
		DirectionOfWhereCameraIsFacing = glm::rotate(CameraQuatBothPitchAndYaw, DirectionOfWhereCameraIsFacing);
		PositionOfEyesOfPerson += CameraPositionDelta;
		CenterOfWhatIsBeingLookedAt = PositionOfEyesOfPerson + DirectionOfWhereCameraIsFacing * 1.0f;
		if (CameraProcessingThreadStarted == true) {
			CurrentCameraViewingSettings.Yaw *= 0.7999f;
			CurrentCameraViewingSettings.Pitch *= 0.7999f;
			CameraPositionDelta = CameraPositionDelta * 0.90f;
		}
		else
		{
			CurrentCameraViewingSettings.Yaw *= 0.5f;
			CurrentCameraViewingSettings.Pitch *= 0.5f;
			CameraPositionDelta = CameraPositionDelta * 0.8f;
		}
		break;
	}
	View = glm::lookAt(PositionOfEyesOfPerson, CenterOfWhatIsBeingLookedAt, DirectionOfUpForPerson);
	ModelViewProjectionMatrix = Projection * View * Model;
	ProjectionViewMatrix = Projection * View;
}
