Project Description Including Results from Prior NSF Support Shape Capture and Modeling for Wrist Dynamics and Ancient Pottery Analysis using Manifold Surfaces and Signed-Distance Volume Images

Computer Graphics Tools for Understanding Tensor-Valued Volume Data: A Painting Metaphor (CCR-96-19649, CCR-9996209). PI: David H. Laidlaw Amount: $139,620 Duration: April 1997 Jan 2001. In this project we developed visualization tools using concepts from oil painting, primarily layering and discrete brush strokes. The work was applied to multi-valued medical imaging data and to 2D fluid flow. Example images from both domains are shown in Fig. 1. The work has been presented at a Visualization ’99 Conference panel session “Sensory Design Issues as a Driving Problem for Visualization Research;” a Visualization ’98 Conference panel session “Art and Visualization: Oil and Water?”, October, 1998; the Brown University Neuroscience Department, October 1998; SIGGRAPH, August 1998; the Naval Research Lab, Washington, DC, May 1998; the Human Brain Project (HBP) annual meeting, NIH, Bethesda, MD, May 1998; the NSF Conference on Computing in the Life Sciences, Pomona College, April 1988; the Brown University Computer Science Department, April 1998; and the University of Southern California, April 1998. Images have also been featured recently in two articles in “IEEE Computer Graphics and Applications” about future directions in scientific visualization. The following publications have resulted from this funding: [21] [38] [35] [41] [2] [24] [39] [43] [1] [3]. The research has involved the following graduate students: Song Zhang, Daniel Keefe, Paul Reitsma, and R. Michael Kirby. The research has involved the following undergraduate students: Jonathan Reiter, Laura Brogach, Charlie Curry, Clifford Elgin, and Jit Kee Chin.
