I'm confusing how to send Oculus rift rotation data
Hello! Oculus Rift developer!
I'm newbie in oculus rift development.
and please understand my bad english.
I have tried to send oculus rift rotation data to opengl model.
If I rotate the oculus rift, cube model in opengl rotate likewise.
so, I used this function
I got yaw, pitch, roll data.
and I send them to cube model after they were changed from radian to degree.
and I used this function in opengl
but It is not working correctly.
Once I tried to confirm yaw, pitch, roll data, they varied continously.
I think that the cause of the problem is that.
I really want your help or advice!!
If anybody knows about it, please teach me all of thing!
Thank you very much!
and I wish you understand my bad english!

pose.Rotation.GetEulerAngles<Axis_Y, Axis_X, Axis_Z>(&hmdYaw, &hmdPitch, &hmdRoll);

and I used this function in opengl
glRotatef(rotationY, 0.0, 1.0, 0.0);
glRotatef(rotationX, 1.0, 0.0, 0.0);
glRotatef(rotationZ, 0.0, 0.0, 1.0);

- do you call glLoadIdentity() at the start of the render?
glMatrixMode(GL_MODELVIEW);
glLoadIdentity(); - Yes, Of course~!!!
I confirmed that the cube rotated.
but Yaw, Pitch, Roll values varies widely.
e.x
When the Oculus rift isn't moving, Yaw, Pitch, Roll data isn't changed. <- this is my thought.
Is it correct? - Euler angles are non commutative. That means the order you combine them in will affect the result.
If the orientation seems wrong, try changing the order of the glRotatef calls.
