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
Los Alamos National Laboratory.
These are images from two mpeg movies
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.
