Interpreting Preview Mode
● Preview mode shows the top down view.
● The preview will be less accurate than the final
reconstruction.
● If you see minor 'drift' then your scan is fine and
the full SLAM algorithm will fix it.
● If you see a major drift (something that looks like
a tornado) then it's possible you rotated too fast
and lost tracking. To be on the safe side you
should stop the scan, and try again.
