| Abstract: | An approach of three-dimensional seismic ray tracing is presented, which is derived from adopting two-dimensional linear traveltime
interpolation (LTI). By adjusting the forward process using the partition of grid interface, and backward step by considering
more directions, the new approach is suitable for the application of three-dimensional models. The calculation results show
that, with the same accuracy, the improved 3-D method is much faster than the method of traditional LTI directly applied in
the three-dimensional case. |
