Images of a Billion-Zone Compressible Turbulence Calculation from Los Alamos National Lab
The following are the quantities referred on this page:
vorticity = |curl(vx,vy,vz)| Color bar
entropy = ln(p/d^gamma) Color bar
compression = -div curl(vx,vy,vz) Color bar

The following are steps in time of a full view of the center of the dataset.
The area renderend is a full (1024x1024) slice through the volume, centered
at the middle. The xy slice rendered is viewed from -z, and is about 25%
of the volume.
