In the usual presentation, the potentials due to a moving charge, the Liénard-Wiechert potentials, are obtained from the retarded potentials expressed in terms of a volumetric charge distributions. It is argued that they may be also obtained from the retarded potentials of a moving point charge, corrected by Doppler like effects accompanying propagated entities, and caused by its motion in relation to the observation point.
