In AndrewHFarkas/EMEGShelper: What the Package Does (One Line, Title Case)

Turns polar coordinates (EPosSphere) into Cartesian coordinates

Description

This function takes polar coordinates (EPosSphere in EMEGS) and turns them into Cartesian 3d coordinates. Assumes radius of one, X is right ear (negative) to left ear (positive), Y positive toward nose, and Z is 1 at Cz. Spherical coordinates are returned in radians and degrees. Theta is 0 at Cz pi at other pole. Phi is zero at right ear, pi/2 (90°) at nose, pi (180°) at left ear, 3/2*pi (270°) at Oz.

Usage

polar2cart(theta_radians, phi_radians)

Arguments

theta_radians	angle in radians from north pole Cz
phi_radians	angle in radians from right ear to nose

Value

Returns a named vector with X, Y, and Z coordinates
