The sample synthetic model named "98" was created during the technical
session of the SW3D consortium meeting in June 1998. The aim of the work
done was not to create a realistic model, but to demonstrate capabilities
of program packages `MODEL`
and `CRT`. The participants
of the meeting were asked how should the model look like and
which computations should be performed. The data and MS-DOS batch files
for the computations were prepared just during the session. It was thus
a good opportunity to learn a lot about both the program packages.
History files to manage the computations using Perl were added later.

History file
`98-mod.h` may be used to display
the structural interfaces and P-wave velocities in the model
in the Virtual Reality Modeling Language (VRML).

File `98-srf.wrl`
contains 3-D view of the structural interfaces in the model.
The interfaces are coloured according to indices of the surfaces
covering them.

File `98-vp.wrl`
contains 3-D view of the "solid" P-wave model, composed
of several P-wave velocity sections.
