Collaborative visualization and modeling

Rapid advances in computing hardware (workstations, PCs), infrastructure (networks, cable, telephone), product development software (geometric modeling, process simulations, graphics), and business models (emerging economies, international currency exchange) have provided the raw material to support true globalization of product development. This globalization in turn raises a strong need for members of an enterprise (design, manufacturing maintenance, sales, management) to exchange product information in a concurrent manner and collaborate throughout the life cycle of families of products. We summarize some of the key issues in computer supported cooperative work (CSCW) related to product development, and then cover some of our ongoing work in collaborative visualization and modeling. On visualization, we cover the collaborative aspects of: (a) geometry based rendering (3DIX) and (b) image based rendering (PanoramIX), and on modeling: (c) solid modeling (procedural solids, shape control), (d) real time reverse engineering (3D reconstruction), and (e) product data management (PM)
