This example involves using the two scanning modes to scan an object that has a nearly cylindrical shape. You can use either mode for
scanning, but rotary scanning achieves the shortest scanning times. The scanning pitch is equivalent for both, but rotary scanning produces
smoother surfaces.
Rotary scanning
Pitch of 1.4 mm x 1.6 degrees
Scanning time of 3 minutes 30 seconds
Plane scanning
Pitch of 1.4 mm x 1.4 mm
Scanning time of 6 minutes
This is an example of an object finished using rescanning after rotary scanning and an object scanned using plane scanning. To determine
which of the two modes to use, you should decide how much you want to take advantage of the features of rotary scanning. Using plane
scanning eliminates the need to perform rescanning, but if smooth curves are important, then rotary scanning may be more effective.
