AbstractVirtual museums provide ways to capture the content of a real museum in a digital (electronic) form and make this digital form more universally available. This paper describes a novel method for digitally recording not only individual museum pieces, but entire museum exhibits (consisting of one or more rooms or spaces). The methodology allows anyone with access to the Internet or a PC to experience anywhere, anytime, any part of the museum's collection or exhibits (past, present and future). Users can explore the museum exhibits in a virtual reality that is both spatially accurate and visually compelling. All objects and 3D scenes are seen in precise full color photographic quality detail. The scene and objects are polygonal meshes representing the surfaces of objects. This permits making measurements directly on the scene with millimeter precision. The methodology, its application to capturing museum exhibits, and examples of exhibits recorded using this technique are described. This work is part of the Virseum project (http://ils.unc.edu/bmh/virseum) at the School of Information and Library Science at the University of North Carolina at Chapel Hill (UNC).In addition to the capture of items and exhibits for virtual access, this methodology opens the door for many other applications, including capturing a record of an exhibit for archival purposes and for communication between curators, and for the design of virtual (never physically implemented) exhibits and pieces based on actual pieces and settings.

Single 2D picture captured from the same 3D scene capture as Figure 2, and seen from the same viewpoint as Figure 2, but with the rendering changed to display the polygon with the interior colors turned off. Thus, objects in the picture seem transparent, and the number of polygons used to depict objects can be appreciated Figure 4. Close-up view of the music books on the piano. The book on the left had a close-up digital image incorporated into the model, while the one on the right did not Figure 5. View from the center of exhibit space of the Plum, Pine, and Bamboo: Seasonal and Spiritual Paths in Japanese Art exhibit. At the center of the image is Tiger in Bamboo, 1861-1863, after Nagasawa Rosetsu, six panel, ink on paper Figure 6. View from outside and above the same exhibit space seen in Figure 5. At the front of the visualization is the entry foyer where the exhibit begins, and continues into a single large room, partitioned into subparts through the use of wall panels. The tiger panel seen in Figure 5 is on the backside of the first freestanding wall panel (slightly green) just beyond the entrance doorway Figure 7. The living room scene shown in Figures 2 and 3 has been modified by adding rough digitizations of two cars ReferencesBaca, M. (ed.)
