The method is based on a three steps process: (i) to carry out a nearest neighbour points coplanarity test and to computate the normal vector; (ii) to find the principal orientation families by Kernel Density Estimation; and (iii) to identify and extract clusters of points belonging to the same discontinuity.<\/p>\n<p>Different sources of information \u2013 synthetic and 3D scanned data \u2013 were employed in this study, being raw source files and obtained results freely provided aiming to a more reproducible research.<\/p>\n<figure style=\"width: 659px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S0098300414000740\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/origin-ars.els-cdn.com\/content\/image\/1-s2.0-S0098300414000740-gr17.jpg\" alt=\"Discontinuity extraction\" width=\"659\" height=\"544\" \/><\/a><figcaption class=\"wp-caption-text\"><sub>Example of clusters identification.
