Title:                Hierarchical Space-Filling Curve Methods in
Massive Data Visualization

Speaker:         Professor Kenneth Joy, Computer Science Department, UC
Davis

Date:              05/16/2005

Time:               3 p.m.

Location:         Calit2 Building, Room 2006

Abstract:         When accessing large data sets from disk during
interaction, performance is highly sensitive to the spatial coherence of
the data layout
and is improved by the use of hierarchical space-filling curves.
Professor Joy will review the use of these space-filling curves in
massive data visualization applications. Hilbert curves can be applied
to applications based on quadtrees and octrees, Sierpinski curves arise
naturally in applications that utilize triangle bintrees, and Z-order
curves can be used in a variety of applications where fast disk access
is necessary. The presentation illustrates the use of these curves in
visualizing massive isosurface data.

Bio:                  Professor Joy is a founding member of the UC Davis
Computer Science department, and specializes in visualization, geometric

                        modeling and computer graphics. He is
co-director of the campus's Institute for Data Analysis and
Visualization and has collaborated on
                        more than 50 publications during the past three
years. Joy is a member of the Association for Computing Machinery, the
IEEE Computer
                        Society, and the Society for Industrial and
Applied Mathematics. He also is a guest researcher at the Center for
Applied Scientific
                        Computing at Lawrence Livermore National
Laboratory.

This event is free and open to the public
