... Visualization of such data has now become a complex 4-D data-mining problem, combining space and time, and finding interesting events in these large datasets. ... NEMO (Teuben 1994) and Starlab are traditional programming environments with which N-body simulations can be setup, run, and analyzed. ... By adding complete orbital information for a select number of stars we have started fully interactive data mining of our 4-D spacetime histories of these star cluster simulations runs. ...
