Topology-based Exploration of Volume Data

When examining a scalar field using isosurfaces, it is often difficult to identify isovalues where relevant isosurface behavior occurs. Using Morse theory, it is possible to identify critical points. These critical points indicate isosurface topology changes: the creation of new surface components, merging of surface components or the formation of holes in a surface component. Therefore, they highlight "interesting" isosurface behavior ... [more]
