Advance Visualization for Seismic Performance—4182003
Mike Bailey (UCSD/F)

One of the obstacles that have held back widespread integrative visualization has been the Tower-of-Babel problem. That is, everyone communicates their results in a different way, forcing specific specialty programs to be written to perform visualization.
