This article is for V2 and V1 3D scanners.
The scanner uses two lasers to scan small to medium-sized objects placed on its rotating bed. One rotation provides 360° coverage of an object. For some small objects, one full rotation (or pass) is enough to scan the whole thing. To capture taller objects, the user can specify in MFStudio how many times the scan head should raise and capture another scan. Like building a virtual layer cake, the scanner can make additional passes until the full height of the object is captured.
During Regular scanning, the bed will rotate forward, but will also sometimes rotate back. This is by design and is called Adaptive Scanning. Its purpose is to capture as much of the object as is physically possible. As new sets of points are captured, the distance between them and the previously-captured set of points is calculated. If too much distance has been detected between the last recorded point, the scanner “backs-up” and re-scans the areas between the two sets of points in an attempt to fill in that distance with additional data.
During +Quickscan points are captured throughout the rotation of the scan bed, up to as frequently as every .125 degrees of rotation. This provides excellent coverage, equal to that provided by Adaptive Scanning. To adjust the frequency of point capture, go into Tools->Options (Mac: MFStudio->Preferences) and check on Enable Advanced Options. This will add Bed Step Override to the scan setup screen, with a slider to adjust the frequency.
There is no scan quality difference between Regular scan and +Quickscan.
