“Supernova” by Marco Ament, Filip Sadlo, and Daniel Weiskopf.

Description: This image presents a rendering of a supernova data set obtained with our ambient volume scattering technique, which was published at IEEE SciVis 2013 [1] and received an Honorable Mention award. Our method approximates global illumination in participating media including scattering and soft shadows, at interactive frame rates using preintegrated light transport.

Compared to traditional volume rendering, our technique provides improved perception of depth and relative size of volumetric features. Furthermore, our method not only provides interactive exploration but also avoids the difficult control of full global illumination. In this example of astrophysical visualization, this allows us to depict the global structure of the supernova as well as its filaments of different scales.

The data set was made available by Dr. John Blondin at the North Carolina State University through US Department of Energy's SciDAC Institute for Ultrascale Visualization.
