Preserve Distance (Coordinates)
This phase updates distance constraints on the specified object so that their desired distance exactly corresponds to the present distance between the two trackers. You have the
option to affect all trackers with distance constraints, or just the trackers with distance constraints that are also currently selected in the pipeline. As a bonus you can also scale the distance value larger or smaller by a factor if desired.
This phase can be used after other phases that change the scale without solving, for example, the two Moving-Obj phases, if you wish to solve the scene yet again, without destroying the constructed scaling. The Preserve Distance phase can be used to update a distance constraint so that scale will not change.
