- Comment/Request
- Comment 14 had a point on the calculation of phi, though he was incorrect in claiming that your equation is "wrong". Your equation is correct but degenerate in that it suffers from gimbal-lock. Your solution for theta has a similar issue. For a solution free of both of these issues, use:
theta = atan2(y, x) % <- ***
% *** - Check implementation in whatever language you are using, most are
% denominator then numerator. Some are not.
phi = acos(z/r)
With this formulation the only degenerate case is a zero length radius, for which the angles are undefined. As such the input is degenerate and the output being degenerate follows.
