Origins of Universe on the Big Screen

Dramatic 3D videos, created from actual data by Stanford University physicists at SLAC's Kavli Institute for Particle Astrophysics and Cosmology, show the origins of the universe. The first step in making a KIPAC visualization is a numerical simulation, an iterative series of physics calculations – often performed on a supercomputer, that determines the composition, distribution, temperature and other properties of matter on a cosmic scale. Visualization Lab Manager Ralf Kaehler then uses rendering techniques, many of which he developed himself, to convert the simulation results into the series of images that becomes the video.
