The wave-propagation demonstration was computed with a finite-difference
solution of the acoustic wave equation shown in class.
It shows a 50 m by 50 m cross-section of wave propagation in a heterogeneous
medium that includes a cavity, such as a lava tube.
You can acquire a QuickTime-format movie of the demo by clicking on the
tube.mov file here, or an MPEG-format
movie by clicking on the tube.mpeg
file here.
The volume demo data are accessible in Sun's VFF format by clicking on the
tubesl.vff file here.
You can display it on a Sun workstation by starting the SunVision application
and selecting the SunVoxel tool. On a Mac you can acquire the
MacCubeView application for viewing the same data.
A Java-based wave-propagation demo is available from a page for
a Seismic Imaging lab exercise.
