whereoptionsare:-search_radius X = sphere radius to be used for finding the k-nearest neighbors used for fitting
(default: 0)
-sqr_gauss_param X = parameter used for the distance based weighting of neighbors (recommended =
search_radius^2) (default: 0)
-use_polynomial_fit X = decides whether the surface and normal are approximated using a polynomial or
only via tangent estimation (default: 0)
-polynomial_order X = order of the polynomial to be fit (implicitly, use_polynomial_fit = 1) (default: 2)
