View relative translation
The View relative translation option provides more natural translation that is relative to the current view instead of being relative to the forward view. For example, normally sideways translation feels inverted when the virtual head is looking backwards, this can be remedied by ticking the Yaw and X checkboxes. The rotation axes that modify the translation direction are optional (Use: Yaw, Pitch and Roll) and the translation axes that are affected are also optional (Apply to: X, Y and Z). The full effect is created when all the checkboxes are enabled, but for those that don't like the way a rotation axis affects translation, it can be disabled and likewise the translation axes that are affected can be disabled. This option has been made fully customisable so that it can be set to taste.
An unfortunate side-effect of view relative translation is that the rotation pivot point is no longer the middle of the head but instead the translation origin centre. So leaning forward and rotating causes the head to swing at a radius from the origin. The TrackIR version of this is called TrueView and is slightly different, it can retain the head pivot location by breaking the absolute translation rule. Instead it uses hybrid relative-absolute translation that behaves relative most of the time but suddenly and sometimes unpredictably switches to absolute when looking towards the origin (to retain the centre position). Neither method is ideal but still a significant improvement for more natural movement.
Numerous TrackIR enabled games implement view relative translation themselves (sometimes optionally), in which case it should be completely disabled in FreeTrack to avoid doubling up, with unpredictable results.

RBflight интересовался, можно ли инвертировать Х при взгляде назад, а его не совсем правильно поняли. И я бы тоже хотел иметь такую возможность.
