NeuroImage Journal Cover Features SCIRun Renderings
The publication and cover image is the result of a close collaboration between the University of Freiburg (Lukas Fiederer, Tonio Ball and others) in Germany and the NIH-funded Center for Integrated Biomedical Computing (CIBC, Moritz Dannhauer) at the SCI institute (Johannes Vorwerk). The cover of NeuroImage' March (128) issue illustrates different tissues in a model of the human head that are known to have distinct electrical properties. In this study, we simulated the electrical effect of blood vessels on current flow originating from active brain regions as monitored by scalp electrodes (encephalography, EEG). Since the understanding of EEG measurements matters in many clinical applications (e.g., epilepsy), SCIRun software offers a set of tools to investigate their underlying electrical generators. Recently, in the new version 5.0 of SCIRun additional capabilities (BrainStimulator) have been added to simulate the current flow from external stimulation devices targeting brain regions of potential EEG generators.

Modeling detonations to transport explosives safely
Researchers modeled a 2005 explosion that left a 30-by-70-foot crater in a Utah highway, capturing the physics that made the truck's cargo explode more violently than it should have. With such simulations, we can design safer transport for explosives. Led by Martin Berzins, University of Utah

Congratulations to Laura Lediaev on winning the 2015 Teapot Rendering Competition. Her stunning image titled Pile of Teapots, was the winner and audience choice award.
This image is not strictly photorealistic. Laura rendered out the image into two main layers, one for specular highlights and caustics, and one for diffuse lighting. She also has a mask for just the teapots, and one for the ground. Laura was able to split up the image and adjust the brightness of each part independently. Here she decided to include some diffuse reflection/refraction for the teapots, but mostly removed the diffuse lighting from the ground. This gave an extra glow to the teapots and also emphasized the caustics. 100,000 samples per pixel.
