Normal Direction

Specify whether or not to use the normal directions of 3D points when judging the connection of the 3D points constituting the 3D blob. Set a value between 0 and 180 degrees.

When the checkbox is checked, if the angle between the normal directions of adjacent 3D points are larger than the threshold, the 3D points are not connectied with each other.
