<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">I have attached an image to this email which depicts what I mean by cut plane and what is produced by the positioning of the cut plane. Now, based on the axes
drawn in the image, Y would be the axis of Roll, Z would be the axes of Pitch and X would be the axes of Yaw. Now you can imagine the cut plane which is positioned at the tip of the cone to be rolling, pitching and yawing.

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Now the orientation of the plane is controlled by a 6DOF sensor. So when the sensor rolls, the plane rolls and the image is rendered correspondingly. Similar
for pitch. Now when the sensor is yawed, the plane remains stationary – that’s the issue at hand. The plane needs to ideally leave the bounds of the box ie. yaw out. As far as pitch is concerned, I have observed the plane moves all the way to the top surface
of the box.<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-left:.5in">Hi Debjit, <br>
<br>
Your question is of the sort that is very difficult to understand without some <br>
sort of visual aid. Do you have any diagrams that illustrate exactly what <br>
you want to achieve? Do you have screenshots to demonstrate what the <br>
system is doing right now? <br>
<br>
