VISUALIZATION FRIDAY FORUM
Fridays, 12pm, LSRC D106
The purpose of the Friday Forums is to build an interdisciplinary
community of visualization experts whose combined knowledge can
facilitate research and promote innovation. Faculty, staff, and
students from across the university meet weekly to share their
research involving the development and/or application of visualization

- Art and/of Visualization
There is a long history of artists' involvement in developing
visualization methods, from the creation of one-point perspective
in the renaissance to the representation of Julia Sets in the
twentieth century. However, the use of technology by artists
is not limited to the concerns of science and engineering. This
talk will explore several recent examples of artistic attempts
to use interactive visualization tools to explore alternative
forms of perception, navigation, and aesthetic experience, often
with provocative philosophical implications.

- Complex Patterns of Motor Activation Changes in the
Brain following Stroke
Unilateral MCA stroke results in a typical pattern of weakness
on the contralesional side of the body. Minimal or no deficit
is see behaviorally in the upper limb ipsilesional to the stroke.
In our research, using functional MRI, we have found stereotypical
patterns of neural activation change associated with moving
the 'unaffected' limb. This seminar will use visualization technology
to illustrate these complex patterns or reorganization in the
brain of patients recovered from stroke.

- Kinemages: Seeing the molecule thru the model
Real-time interactive computer graphics is a very powerful way
to visualize and study 3D molecular structures. However, individual
molecules are smaller than the wavelength of visible light so
there is no such thing as a realistic depiction and multiple
representations are suitable and useful. The molecules are composed
of thousands of atoms connected in a complex but precise arrangement
with little symmetry and no right angles, that form compact
structural domains. The details of local 3D interactions confer
biological function. We will show how our graphics tools have
been optimized for perceiving those 3D relationships: by emphasizing
interactive performance, by tuning colors and depth cuing, and
by providing multiple representations, animations for comparisons,
and contact analysis to evaluate changing conformations.

- Discussion of Scientific Visualization with AVS/Express
AVS/Express is a data analysis and visualization software package
available to NC academics at no additional charge through the
North Carolina Supercomputing Center. AVS/Express has a network-base
graphical interface to build the visualization "program". This
talk will provide an overview of AVS/Express functionality and
highlight some example applications from Chemistry, Astrophysics,
Biomedical Engineering and Environmental Sciences.

- Applying Computational Geometry to Understand Protein-Protein
Formation of protein-protein complexes rank among the most important
and least well understood molecular phenomena inside the cell.
Central to the understanding of the interactions leading to
complex formation is characterization and analysis of the interfaces
formed between proteins. This talk will focus on an interface
construct based upon concepts in computational geometry which
is being applied to 3D protein structural data in an effort
to elucidate the details of protein-protein interactions.

- Networks, Wet Labs, and Forests: An effort towards
integrating and visualizing the physical spaces of Duke
More and more administrative questions lend themselves to being
answered by the visual representation of data.
This talk will describe some of the traditional and emerging
uses of data visualization to help get Duke's business accomplished
and discuss ways we might approach these tasks.
- Where can you find wireless network access on campus?
- How much lab space do we have (and where is it!)?
- "Let me explain why - I - need more lab space to do my

Durham County's tax maps?

- Visualization using Geographic Information Systems
In this presentation we will demonstrate visualization of geographic
data using raster, vector and Triangular Irregular Network models
for terrestrial and marine applications. We will demonstrate
planar geographic displays, "3D" renderings and dynamic flythroughs
for environmental data representation and analysis. We will
also demonstrate applications of internet map server technologies
for the delivery of GIS visualizations to clients on a distributed

- Baying at the Moon: Implementing Luna Imaging's Insight
at Duke University
Luna Imaging Inc.'s Insightr software (www.lunaimaging.com)
allows organizations to manage, access, use, and present digital
collections using the Internet. John Taormina, Director of the
Dept. of Art and Art History's Visual Resources Center (VRC),
will discuss the VRC's role in the implementation of Insightr
as the visual component of Duke University's comprehensive digital
library initiative. With the support of the Perkins Library
and a CIT Grant, the VRC developed an Insightr "collection"
of approximately 4,000 digital images and data records between
May and December 2002, as part of the Insightr startup at Duke,
for two art history courses offered in Spring 2003 (Introduction
to the History of Art I and Chinese Buddhist Art). The initial
development and continuing growth of the art history Insightr
collection, the acquisition of a comprehensive text database,
metadata issues, data standards, and workflow procedures will

- Using Vis5D in Environmental Fluid Dynamics
Environmental fluids (atmosphere and water) have a complex three-dimensional
structure that varies rapidly with time. To better understand
and interpret the behavior of these fluids, it is essential
to use sophisticated visualization software. In this seminar,
a demonstration of the use of Vis5D for atmospheric, ocean and
lake dynamics will be illustrated.

- The Oral Tradition in 3D: Harold Innis, Information
Visualization and the 3D Virtual Buildings Project
One of the key challenges that historians face -- especially
at the university level -- is enabling students to see the proper
relationship between a historical representation, and the object
or event to which it refers. Most students see an absolute correspondence.
Historians seek to show them that the relationship is necessarily
imperfect. In this talk, I present the efforts of the 3D Virtual
Buildings Project to engender in students a more sophisticated
understanding of the strengths and limitations of historical
representations, be they books, articles, or 3D models. I will
show the project's debt to the writings of the Canadian communication
theorist Harold Innis, who noted that not all forms of communication
are equal in their capacity to represent a concept. I will also
demonstrate the project's pedagogy, namely use of the process
of 3D computer model construction to enable students to see
the proper relationship between model and referent.

- Syzygy: a Framework for Distributing VR Applications
The many interactive components of virtual reality applications
require demanding computation and organization of information.
Syzygy provides a framework for distributing the application
to a diverse set of machines in order to coordinate the interactive
components, rendering, and data collection.
