Science, faithfully rendered

visualization

This image shows the path of water through the karst limestone structure of a ground sample taken from south Florida. The photorealistic shading enhances the analysis of the stone porosity and the spatial arrangement of the flow traces.

Visualization experts at TACC, the University of Utah, the University of Oregon, Intel and ParaView teamed up to build a visualization tool called GraviT that can render the massive datasets produced by some of the largest supercomputers in the world.

turbulent structures that form as a fluid proceeds through a channel rendered through ray tracing

This image shows turbulent structures that form as a fluid proceeds through a channel, such as air moving through a duct or water moving through a pipe. The efficiency of ray tracing allows for these structures to be rendered in simulations of massive scale.

visualization of turbulent mixing of two fluids

This image shows the turbulent mixing of two fluids in a Richtmyer-Meshkov instability problem, where fluids of different densities are accelerated simultaneously. The photorealistic shading provided by ray tracing makes the turbulent structures and their interrelations more readily apparent. Ray tracing also enables realistic material interactions in the visualization, which provides the refractive and magnification effects visible in the panes of glass inserted through the turbulence data.
