Four terabit visualizations - two presentations about visualizing multi-variate ocean and sea-ice dynamics at high temporal frequency in real time and at distributed locations.

SIGGRAPH 2006

Two talks in a special session at SIGGRAPH 2006 highlighted advanced visualization of ocean and sea-ice dynamics employing Hyperwall installations at NASA Ames and at M.I.T. The visualizations capture multi-variate correlations among processes related to atmosphere ocean exchanges of energy and mass. Technology developed at NASA Ames was used to generate these visualizations in real-time so that 48 different data streams could be viewed simultaneously at high temporal frequency and spatial resolution. The streams were extracted from a 1920 processor ocean and sea-ice model as the computation was being performed. Visualizations were displayed on a forty-nine panel hyperwall at NASA Ames and simultaneously transmitted to a smaller sixteen panel hyperwall installation at M.I.T.
