+Hi everyone!
+
+In the extreme version of OpenTrack-2.3.12, the Octopus pose is still displayed incorrectly.
+The pose-widget is responsible for displaying the Octopus pose in OpenTrack. I have fixed this widget.
+
+Fixed bugs:
+- The turns and movements of the Octopussy are now performed truly independently of each other, as it should be in 6DOF.
+- When cornering, there is no "gimbal lock" at Pitch = +/- 90 degrees.
+- Fixed directions of axes of rotations and positions. Now the Octopus pose displays the actual direction of view on the plane.
+- Fixed display of the back (green) surface of the Octopus. Previously, it was displayed mirrored.
+
+Additional features:
+- Applied "perspective projection", the picture becomes more voluminous.
+- Added lighting effect from above, with the same purpose.
+- Added background fill for the widget. This makes it possible to see the borders of the widget.
+- Added X and Y axes. This helps to estimate how far the Octopus is deviated from the center.
+- Added [Mirror] checkbox, mirroring positions and rotations. It is often more convenient to observe the Octopussy's mirror pose.
+- If before compilation in the file "pose-widget.hpp" include line 19: "#define TEST", then a rectangular frame will be drawn around the Octopus. This is useful when testing a pose-widget to assess distortion and size.
+
+The corrected pose-widget now displays the Octopus pose correctly and can be used to check OpenTrack settings, sometimes even without launching the flight simulator.
+
+A video of the corrected pose-widget is available here:
