pointCloudHandle (int): handle of the point cloud
iterations (int, default: 4): number of iterations
neighbors (int, default: 12): number of neighbors a point's neighborhood should contain on average
samples (int, default: 300): number of points sampled to estimate the neighborhood radius
squared_radius (float, default: 1.0): neighborhood squared radius used for principal component analysis. if this is positive, neighbors and samples will be ignored
