WebThe basic principle underlying the method is that a wavefront can be evolved by repeated application of local ray tracing from a set of points lying on the wavefront surface. Thus, for some given time step δt, a new wavefront is deﬁned by the end points of the rays traced from the old wavefront, as illustrated schematically in Fig. 28.
