This registry entry defines the intensity (strength) of the smoothing in units of length. During the smoothing process, the software moves points, taking into account the coordinates of the neighboring points. When scanning in mm units, tests show that 0.25 is a good value for most parts. When scanning flat parts, you can obtain better results with a slightly higher value.
