inverse kinematics are much more effort to implement. Basically in
POV Ray terms you are doing forward kinematics all the time when you
say something like {object ARM rotate 30*x}. Inverse kinematics means
specifying where the hand should be and then automatically calculating
the required rotations for all joints along the way.
