SUMMARY:Cinematic visualization of large simulation datasets
DESCRIPTION:Guillermo Marin (Barcelona Supercomputing Center, Universitat 
 Autònoma de Barcelona) and Miguel Esteban (Barcelona Supercomputing Center
 )\n\nScientific visualization software often lacks advanced rendering engi
 nes for photorealistic results, and fine control over the final quality of
  the image. In contrast, cinematic software provides extensive control ove
 r every aspect of image creation, as well as physically based rendering (P
 BR) capabilities, but lacks the ability to load and process scientific dat
 a in a controlled and accurate manner. This session presents a visualizati
 on pipeline that communicates computer simulation results with Visual Effe
 cts software, enabling the creation of high-end visualizations that are bo
 th scientifically accurate and visually compelling. One implementation of 
 the pipeline is based on a multi-resolution variation of the OpenVDB forma
 t for the efficient handling and rendering of large volumetric data, with 
 examples from computational fluid dynamics simulations. A second implement
 ation is a particle-based data-reduction method, with examples from cosmol
 ogical and climate simulations. The pipeline runs in HPC architectures, in
  order to minimize data transfer bottlenecks.\n\nDomain: Applied Social Sc
