Determines the 'concave' hull of a set of points.
Inspired from JIN-SEO PARK AND SE-JONG OH, "A New Concave Hull Algorithm and Concaveness Measure for n-dimensional Datasets", 2012 Calls extractConvexHull2D (see associated warnings).
| points | input set of points |
| hullPoints | output points (on the convex hull) |
| contourType | type of contour (above / below / full) |
| allowMultiPass | whether to allow multi-pass process (with longer edges potentially generated so as 'disturb' the initial guess) |
| maxSquareLength | maximum square length (ignored if <= 0, in which case the method simply returns the convex hull!) |
| enableVisualDebugMode | whether to display a (debug) window to represent the algorithm process |
| maxAngleDeg | max angle between segments (angle between 0 and 180, in degrees) |
at least one of the new segments must be smaller than the initial one!
