While doing a lot of tests with different objects now, I would like to have a mode where the scanner tries to retrack, but does not create new points, neither while tracking nor when it thinks it has found the track back. I ruined quite a lot of perfectly fine scans already, just because I tried to scan the last details from the top or bottom, the scanner lost the track and either produced a lot of artifacts while trying to retrack or suddenly starts scanning, but has the track actually wrong. “Undo” doesn’t work really good either, and when this happens for the 6th time in the same position, I tend to just give up, to be honest.
I tried a different approach: start with a position the scanner knows already and finds back immediately, than slowly tilt the object into the target position, thoroughly watching whether the scanner looses the track. Sometimes this works, but more often the scanner looses track while I am tilting the object and suddenly starts producing wild artifacts, see above.
What I would like to have in the software to solve this problem, is a mode where the actually scanning - meaning the production of new points - is paused, but the tracking is still active. In this mode I can try as many times as neccessary to bring the object into the new position, without having to fear that the scanner suddenly produces lots of artifacts.
That could still be frustrating when the scanner/software keeps getting the track wrong, but at least would prevent adding erratic stuff to the object partly scanned up to this point, which need to be removed with much effort.
