RESEARCH
Visualization Rendering
Research, design and development of
custom advanced rendering software for visualizing high-dimensional scientific
data. Techniques include physically-based, distributed ray-tracing, GPU (GLSL)
hardware shading, integration of volumetric, geometric, quadric, lines, and
points in a single scene, abuffer particle system
integration, bi-directional reflectance functions (BRDF), volume scattering
with real-world absorption, scattering, and emission properties and volumetric
phase functions, deep-map shadows, non-photorealistic rendering, motion blur,
depth-of-field, key-frame animation editor, color-map editor, ambient
occlusion, and support for 360 degree spherical projection VR display. Software
system has been used to visualize data from a variety of computational
simulations including density currents, turbulent boundary layers, hurricane
development, binary neutron stars, 3D Rayleigh-Taylor instabilities,
tornado-producing thunderstorms, wind-farm simulations, and AMR (adaptive mesh
refinement) galaxy clusters. This work has been featured in the book Visual
Computing, publications including Computer Graphics World, Physics
World, and Astronomy
Magazine, and presentations at SIGGRAPH, XSEDE, PEARC and Supercomputing
conferences. Click thumbnails for imagery.

Visualization
Representation
Research and development of
representation methods and algorithms to visualize high-dimensional scientific
data. Particle is a particle systems generator and
renderer to provide a more accurate and realistic representation of
high-density vector data. This software was developed to simulate the
results achieved from real-world smoke chamber tests as a way of analyzing
complex, high-density vector data. The system has been successfully used
to visualize astrophysical gas dynamic data and wind data circulating around
structures and in film Data-Driven
shown at SIGGRAPH 1993
Electronic Theater. Vsurf generates iso-surfaces from volume data. The
algorithm used to determine polygonal surfaces is an implementation based on
the method described by Wyvill, Wyvill, and McPheeters in Visual Computer
- August 1986. The software eliminates the common holes problem within
surfaces generated from the popular Marching Cubes algorithm. Program was
used for various visualization productions and images and in film Caustic Sky shown at SIGGRAPH
1992 Electronic Theater. Click thumbnails for imagery.

Collaborative, Remote
Visualization
Researched and developed a C++ API
to provide scientific visualization functionality in a collaborative,
heterogeneous computing environment. Applications written with this API
were capable of operating across a spectrum of platforms including virtual
reality environments (i.e. CAVE, IDesk, IWall), graphics workstations, personal computers, or
within a web browser. Software provided applications with the ability to
share information among participants through standard message passing. Use
of this API allowed application developers to write, without requiring prior
knowledge, programs that render and display across different software and
hardware architectures. Software also provided the capability for participants
to remotely view a rendered scene in a standard web browser. Click thumbnail
for imagery.
Virtual Workplace
Designed and co-developed a
distributed, shared, 3D virtual workplace environment that served to prototype
next generation workspaces. This research was demonstrated at the Andersen
Consulting Global Consulting Seminar. This system provided shared agent
representations of users within a graphical world of interactive, 3D
information spaces enabling users to share, point, and view one another. Click thumbnail for imagery.
Information
Visualization
Initiated and developed research initiative within Andersen
Consulting's Center for Strategic Technology Research to visualize abstract
information spaces. Involved tool development and collaborative client
projects to represent business information in intuitive, multi-sensory
forms. Produced and animated film showing the economic growth of
industries within Andersen Consulting over a five year period. Film
showcased at annual Partner conference. Click thumbnails for imagery.

Toon Extraction
Research and development of
software tools to extract and re-use information from 2D hand-drawn cel
sequences for 3D applications and game creation. Motion Mapper maps 2D cel-animated, character motion to 3D joints and
skeletons used in standard 3D animation packages. Software also employs
FFT transformation on the input data by filtering in the frequency domain to
reduce and remove input noise as well as alter the motion. Contour Extractor extracts outlines of painted regions from 2D
digitized cel images. Software employs visualization principles of
iso-contouring to identify and contour painted regions
based on color information and writes out outlines as
geometry for interactive viewing or use with standard animation packages. Shadow generator automatically
generates shadows (body and cast shadows) from 2D cel-animated character
sequences. Software uses input such as light direction, coverage, shadow
colors and opacity and outputs shadow files to composite for final game
animation sequences. Click thumbnails for imagery.

Music
Information Design
Researching and implementing
techniques, methodologies, and tools for developing novel forms of designing
information in the areas of music, music education, and the jazz genre.
Techniques include metaphorical music mapping (using visual metaphors and human
body movement to map and convey melody, harmony, rhythm), mapping musical
concepts (such as note frequency and target notes) outside scope of standard
notation, representing relationships between sound and music, intensity mapping
and harmonic palettes, complementing visual design with ASL (American Sign
Language), bar-coded representations (shape/proportion mapping for
visualization of song structure and instrumental relationships). Software
development includes midi processor, 3D animation system plug-ins, and music visualization
system. Click thumbnails for imagery.

Space-Time
Synthesis
Exploring spatial and temporal simultaneity
and employing time as a design element for developing new forms of
informational and abstract designs. Investigating methods such as simultaneous
display of time-based events, missing and replacing time sequences, interlacing
spatial fragments, and juxtaposition of time-based events spatially in
three-dimensions to represent information through multiple perspectives. Exploring
novel methods of non-linear sequencing and frame-rate modification to allow for
emotion, narrative, and expression. Software system allows designers to move a
plane through three-dimensional space of time-based sequences at different
speeds to create new sequences. Time-based imagery can be synchronized to a
music track through expressive movement to create new sequences with music. Click thumbnails for imagery.

Virtual Reality
Designed,
developed, and taught a unique course in CAVE Virtual Reality programming using
the CAVE at the National Center for Supercomputing Applications. Offered to
computer science students at both the University of Illinois and Parkland
College, this course required students to design and develop their own CAVE
applications. At conclusion, these applications were then showcased to the
public at the annual University of Illinois Engineering Open House. Many of
these student applications continue to be demonstrated today for various tours
and visits.
Digital Media
Designed and developed degree program and curriculum in motion
graphics, 2D/3D computer animation, gaming, web development, and graphics
programming. Program offers unique blend of art, design, film, and computer
science courses with various specialized tracks. Graduating students have been
employed at prestigious national and local companies and institutions such as
Industrial Light & Magic (feature film/effects), Rhythm & Hues (feature
film), 2K Sports (3D gaming), the University of Alabama (scientific visualization),
Frasca (local 3D flight simulation) and Volition Inc. (local 3D gaming).
