openlifu.geo.spherical_to_cartesian¶

openlifu.geo.spherical_to_cartesian(r: float, th: float, ph: float) → Tuple[float, float, float][source]¶

Convert spherical coordinates to cartesian coordinates

Parameters:

r – the radial spherical coordinate
th – the polar spherical coordinate theta, aka the angle off the z-axis, aka the non-azimuthal spherical angle
ph – the azimuthal spherical coordinate phi

Returns the cartesian coordinates x,y,z

Angles are in radians.
