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.
History file 98-ss.h, calculating synthetic seismograms, also generates file 98-ray.wrl containing 3-D VRML representation of the corresponding 2-point rays.
