During registration, SCENE designates the first scan as the reference
scan, and all subsequent scans are aligned to this reference scan. Each
scan position contains a small amount of error (±2 mm), and this error
accumulates with each subsequent scan.
While the first scan has an error of ±2, the second scan has an error
of ±4, the third scan has an error of ±6, and so on. This can lead to a
significant amount of error after several scans.

The accumulation of error can be mitigated by using the Closed Traverse
strategy.
