On-going Projects

Financial Visual Analytics (Remco Chang, Bill Ribarsky)

In collaboration with Bank of America, we develop tools to visually analyze international wire transactions in order to detect suspicious and fraudulent activities. WireVis employs multiple coordinated views in a highly interactive manner and depicts relationships of different nature between the transactions. read more...

Knowledge Visualization (Dong Hyun Jeong, Tera Green, Bill Ribarsky)

Geospatial Visualization (Remco Chang, Tom Butkiewciz, Bill Ribarsky)

Rendering or visualizing large expansive terrain or urban models has been a great challenge in computer graphics and visualization. In this project, we are interested in the issues of rendering large geospatial data, visualizing changes over time, highlighting potential error, and depicting relationships between the data. read more...

Stereoscopic Displays and 3D Interaction (Zach Wartell, Bill Ribarsky)

We are developing a variety of large screen and semi-immersive stereoscopic environments. Our goal is to achieve optimal stereo viewing even under head-tracked conditions for very deep virtual environments where scale can change by several orders of magnitude. Optimal stereo viewing must also be achieved under diverse modes of interaction, especially direct 3D manipulation of objects in the scene. Read more on Stereoscopic Display and 3D Interaction

Previous Research Projects

Virtual Geographic Information System (VGIS) (Zach Wartell, Bill Ribarsky)

VGIS is a large, multifaceted project to allow navigation of and interaction with very large and high resolution, dynamically changing databases while retaining real-time display and interaction. The system allows users to navigate accurate geographies (less than 1 meter resolution in some cases) with sustained frame rates of 15-20 frames per second. read more...

Mobile Situational Visualization (Cynthia Zhang, Zach Wartell, Bill Ribarsky)

In combat zones, it is critical for personnel to share info of risks and follow an optimum path to the destination location. Our research is to explore the effectiveness of a Risk Minimization Path Planning Algorithm (RMPPA) to generate accurate feasible routes with connection to a 3D real-time risks info database on the Virtual Geographic Information System (VGIS). In this project, we apply RMPPA to a Mobile Path Engine (MPE) in VGIS. read more...

Genomic Visualization (GVis) (Dong Hyun Jeong, Bill Ribarsky)

GVis (A Scalable Visualization Framework for Genomic Data) is an interactive environment with which it is possible to quickly explore the phylogeny hierarchy of organisms from the highest level down to the level of an individual organism of interest and also analyze interesting nucleotide sequences by initiating gene-finding and gene-match tools. read more...
