The result is an unoriented normal for each input point. The output of the normal estimation algorithm highly depends on the \ccc{k} parameter. -The number of neighbors controls the size of the point subset considered for plane fitting at each input point. As this parameter is application-specific we do not provide any default value. For noise-free point sets this value can be set to a small number, e.g., 15. Larger values (e.g., 30 or more) lead to smoother normal fields and are more time consuming. We thus recommend using them only for noisy data sets. +The number of neighbors controls the size of the point subset considered for plane fitting at each input point.
