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.

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.

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.

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.

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.

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.
