Filter by ball
Point cloud|Ball
The function filters (erases) points by a bowl with a certain radius. A point will be reduced if the bowl cannot be dropped from above (or from below depending on which side that has been selected) so the point will be hit, without the bowl first hitting another point.
Imagine a bowl rolling under a point cloud. The points tangent by the bowl are the points that will remain in the point cloud, the rest will be erased. Select different radius to add more/less points.
Precision decides how large steps the bowl "rolls" over the surface - higher value means faster filtration.
