skspatial.objects.Sphere.to_mesh¶

Sphere.to_mesh(n_angles: int = 30) → Tuple[ndarray, ndarray, ndarray][source]¶

Return coordinate matrices for the 3D surface of the sphere.

Parameters

n_angles: int: Number of angles used to generate the coordinate matrices.

Returns

X, Y, Z: (n_angles, n_angles) ndarray: Coordinate matrices.

Examples

>>> from skspatial.objects import Sphere

>>> X, Y, Z = Sphere([0, 0, 0], 1).to_mesh(5)

>>> X.round(3)
