Texas Advanced Computing Center (TACC) researcher Paul Navratil, with support from the U.S. National Science Foundation (NSF), is leading an effort to design GraviT, a new framework that would enable tens of thousands of scientists and engineers who use the U.S.'s supercomputers to add ray tracing visualizations to their research, regardless of the type of computing systems or hardware they are using. Ray tracing simulates the photons of light as they bounce from a light source off an object and into the eye, based on the laws of optics. Ray tracing's physically realistic rendering creates more realistic reflections and shading than rasterization-based visualizations, and helps people understand the spatial relationships between the parts of the visualization. In addition, since the objects being rendered are described computationally, they also are more scientifically accurate. GraviT automatically recognizes the type of problem a researcher is working on, and then appropriately distributes data from the simulation to multiple computer processors for visualization.
