mosaic.parametrization.Sphere

class Sphere(radius, center)

Bases: Parametrization

Parametrize a point cloud as sphere.

Parameters:

radiusnp.ndarray

Radius of the sphere

centernp.ndarray

Center of the sphere along each axis.

__init__(radius, center)

Methods

__init__(radius, center)
compute_distance(points, **kwargs)	Computes the distance between points and the parameterization.
compute_normal(points)	Compute the normal vector at a given point on the surface.
fit(positions, **kwargs)	Fit a parametrization to a point cloud.
points_per_sampling(sampling_density[, ...])	Computes the approximate number of random samples required to achieve a given spatial sampling_density.
sample(n_samples[, normal_offset])	Samples points from the surface of a sphere.
