Noise - a Near Optimal IsoSurface Extraction algorithm for large dataset. Noise was designed mainly for unstructured grids, though it is also near optimal for structured grids, and utilizes a new concept we call the Span Space. Noise is now part our computational steering SCIRun software and the parallel renderer at the Advance Computing Laboratory (ACL), Los Alamos National Laboratory.

These are images from two mpeg movies (1.8MB and 4MB) on Mantle Convection Modeling which was done on a Cray T3D supercomputer at the ACL using over 20 million finite elements. The first image shows a single, red, isosurface while the second has two isosurfaces, red and blue, and uses transparency. The third image shows a slice through the mantle with a single isosurface.
