摘要
Different traveltimes are identified as viscosity solutions of the eikonal equation on locally selected domains called big rays. Big rays are constructed by an ad hoc algorithm based on a coarse ray tracing. Viscosity solutions in the big rays are computed using an upwind finite difference scheme. This hybrid method allows an easy and fast computation of multivalued traveltime fields. (C) 1996 Academic Press, Inc.
