Abstract
We use a ultra-high-resolution wall display to make it easier for analysts to visually compare and contrast different simulations from a deep water asteroid impact ensemble dataset. Thanks to their very high pixel density, these physically large surfaces enable users to display multiple simulations simultaneously, juxtaposing multiple perspectives on the data for each of them. Playback of the different simulations can be synchronized. Changes of perspective on the data, made interactively in one view by users, can also be applied automatically to the corresponding views in the other simulations.
