Partnership for Research In Stereo Modeling (PRISM)
Established in Spring 1996 at Arizona State University to promote interdisciplinary research in 3D Data Acquisition, Visualization & Modeling, and Form Realization.
PRISM includes researchers with a shared interest in visualizing 3D and higher dimensional data. Disciplines include: Anthropology Archaeology Biology Computer Science Educational Technology Fine Arts Industrial Engineering Mechanical Engineering
