Abstract

Seismic data obtained from surface observations of the Earth and the Sun has enormous importance in increasing our knowledge of the in- ternal structure of these objects. By making special assumptions (e.g. spherical symmetry) it is possible to use analytic tools or relatively sim- ple numerical calculations to analyze the tomographic data. In both cases, however, the real problem is inherently three dimensional and to resolve detailed structure enormous amounts of data are required. We show in this paper how visualization can aid the process of in- terpretation. The spherical geometry of such objects, and the huge variations in physical quantities with depth, present formidable chal-lenges to current visualization systems. We present a major case study using AVS/Express to visualize some of the largest geophysical simula-tions ever created and show how we intend to extend these techniques to astrophysics.
