Abstract
A globally valid time-domain expression relating a wavefield to a multi valued ray field with caustic singularities is given. The input for the wavefield computation is generated by linear interpolation in the phase space of the parameters obtained by tracing a densely sampled ray field. The singularities at p-caustics are also properly handled.
