The ViDi Center for Digital Visualization


The ViDi Center will fundamentally address the connections between visual analysis and re-synthesis problems, primarily involving 3D objects and environments that pose significant and interesting questions in the Humanities (but also in Medicine and Engineering). The ViDi Center will bring together Engineering and Humanities faculty to embark on deeply collaborative investigations to discover new Computer Graphics modeling and animation methods and apply the best and most appropriate techniques to modeling and visualization challenges presented by human artistic, structural, and cultural artifacts.

Research Interests

Ph.D. Research at University of Toronto in computer understanding of three-dimensional moving object motions from movie images; this work was the first to build general 3-D motion models from perspective image sequences. Early research at University of Pennsylvania into effective methods for graphical representation of complex objects using solid and surface models. Speciality in human figure modeling and animation, especially with respect to the problems of motion specification and control. Recent research centers on virtual embodied human agents, including fast motion generators, Parameterized Action Representation (PAR), Parameterized Behavior Trees (PBT) and functional crowd simulation . The Center for Human Modeling and Simulation is the creator of the Jack software, used worldwide for human figure animation and human factors analysis. Jack is now commercially licensed by Siemens (which bought UGS, which bought Unigraphics, which bought Engineering Animation, Inc. which bought the first commercial home of Jack, Transom Technologies, Inc.).  More recent work on Digital Visualization in the humanities, through the ViDi Center.  A focus on reconstructing and peopling ancient societies, especially in South America, with Anthropology colleague Clark Erickson.

Quotes that shaped my academic life.

Coincidences -- True vignettes


Home repair, cooking and baking, dachshunds, stained glass, travel, and Philip Glass.

If you want to visit Schatze [RIP 8-29-02 at almost 17 years], Greta [RIP 9-17-04 at 14 years], Bruiser [RIP 3-11-01 at 12 years], and Holly [RIP] (clockwise from bottom), click here. How about Playful Bruiser? Or maybe Bruiser as the Cane-Doge. "Puppy" Josef.  Our first rescue dachshund: Kohle (a "standard") [RIP 1-5-15].  Our second rescue: Magda (a white dachshund; a former breeder bitch from Texas) [RIP 2-11-13].

Josef discovers "Squirrel TV" while Greta thinks he's very silly.
