vector2xy#

classmethod GnomonicProjection.vector2xy(v: Vector3d | ndarray) → ndarray[source]#

[Deprecated] Convert from 3D cartesian coordinates \((x, y, z)\) to 2D Gnomonic coordinates \((x_g, y_g)\).

Parameters:

v: 3D vector(s) on the form [[x0, y0, z0], [x1, y1, z1], ...].

Returns:

gnomonic_coordinates: Gnomonic coordinates on the form [[x0, y0], [x1, y1], ...].

Notes

Deprecated since version 0.8.0: Function vector2xy() is deprecated and will be removed in version 0.9.0.

Examples

>>> import numpy as np
>>> from kikuchipy.projections import GnomonicProjection
>>> v = np.random.random_sample(30).reshape((10, 3))
>>> xy = GnomonicProjection.vector2xy(v)
