The advent of modern Graphics Processing Units (GPUs) with their high degree of parallelis
m is causing
major shifts in the efficiency of algorithms

in computer graphics and scientific visualization. Techniques
that were

previous
ly

seen as too slow for mainstream use can now be made practical. GPU
-
based
implementation of these algorithms is ofte
n non
-
trivial, because the same features that make the GPUs
so fast also cause them to be hard to target for algorithms. Trying to exploit the high levels of bandwidth
and float
ing
-
point performance available turns out to be quite hard, since the general "
flow" of the
algorithms has to be substantially modified to enable efficient execution.


In this talk, I will describe recently developed GPU
-
based algorithms for several important scientific
visualization tasks, including isosurface generation, and volum
e rendering of unstructured grids. I will also
discuss the application of these techniques on the visualization of spatial and temporal data from a
complex environmental observation and forecasting system for the Columbia River.


Biography


Claudio T. Silv
a is an Associate Professor of Computer Science at the University of Utah. Before joining
Utah in 2003, he worked in industry (IBM and AT&T), government (Sandia and LLNL), and academia
(Stony Brook and OGI). He received his Ph.D. in Computer Science from t
he State University of New
York at Stony Brook in 1996, and his B.S. in Mathematics from the Federal University of Ceara (Brazil) in
1990.


He co
-
authored over 60 technical papers and 4 patents. He serves on the editorial board of the
IEEE Transactions on
Visualization and Computer Graphics, and on numerous program committees. He
was co
-
chair of IEEE Symposium on Volume Visualization and Graphics 2004 and the IEEE Symposium
on Parallel and Large
-
Data Visualization

and Graphics 2003. He will be papers co
-
cha
ir of the IEEE
Visualization 2005.
