Generate synthetic points to fill holes in point clouds.

points : (Mx3) array

The coordinates of the points.

max_circumradius : float or int

A triangle with a bigger circumradius than this value will be considered to be a hole, if the triangle also meets the max_ratio_radius_area requirement. Default: 0.4

max_ratio_radius_area : float or int:

A triangle with a bigger ratio between the circumradius and the area of the triangle than this value will be considered to be a hole, if the triangle also meets the max_circumradius requirement. Default: 0.2

distance : float or int

The distance between the points that will be added. Default: 0.4

percentile : int

The percentile of the Z component of the points neighbouring a hole to use for as the Z of the synthetic points. Default: 50 (median)

normals_z : array-like of float

The Z component of the normals of the points. Will be used to determine which points should be considered when determining the Z value of the synthetic points. Default: None

min_norm_z : float or int

The minimal value the Z component of the normal vector of a point should be to be considered when determining the Z value of the synthetic points. Default: 0

bounding_shape : str or Polygon

A shape defined by a polygon WKT string or a shapely Polygon. No sythetic points will be added outside this shape. Default: None

height_clustering : bool

Option to cluster the triangles based on height using a KDE to prevent triangles at different heights from ending up in the same polygon. Default: False

kde_bandwidth : float

The bandwidth of the kernel during kernal density estimation for clustering. Default: 0.05

suppress_qhull_errors : bool

If set to true an empty array will be returned when qhull raises an error when creating the delaunay triangulation.

synthetic_points : (Mx3) array

The synthetic points
