openlifu.geo.cartesian_to_spherical_vectorized

openlifu.geo.cartesian_to_spherical_vectorized(p: ndarray) → ndarray

Convert cartesian coordinates to spherical coordinates

Parameters:

p – an array of shape (…,3), where the last axis describes point cartesian coordinates x,y,z.

Returns: An array of shape (…,3), where the last axis describes point spherical coordinates r, theta, phi, where

r is the radial spherical coordinate, a nonnegative float. theta is the polar spherical coordinate, aka the angle off the z-axis, aka the non-azimuthal spherical angle.

theta is in the range [0,pi].

phi is the azimuthal spherical coordinate, in the range [-pi,pi]

Angles are in radians.
