-\note This algorithm does not find all types of self-intersections. It is tuned
-      to detect vertex/vertex, vertex/edge, edge/edge, vertex/face and edge/face
-      intersections. Face/face intersections detection is switched off as it
-      is a time-consuming operation that gives an impact on performance. To find
