“…To acquire multiple-view images, we used the 3D capturing system 13) . The system has a PCcontrolled robot arm and a turntable, and it can capture images from arbitrary viewing points of almost all of the upper half of a target object placed on a turntable.…”

An algorithm for reconstructing photorealistic 3D model from multiple-view images is proposed. The idea is based on the surface light field approach. In the algorithm, a geometric model is reconstructed as a visual hull using an image-based multi-pass algorithm we have developed, then the hull is represented as a quadrilateral-meshed surface. Next, colors of input images are assigned onto each vertex according to viewing directions using a new data structure we have developed. The structure is a hexagonal tessellation based on expansion and replacement of a buckyball. Finally, the hexagonal tessellation is represented as a hexagonal image whose pixels represent colors of corresponding input images. Experimental results for real objects show that 3D data can be successfully generated automatically in a short time and that photorealistic data can be viewed from arbitrary viewpoints even for objects with reflective or translucent surfaces.

“…One system closely related to the Boom Chameleon is the room-scale Art+Com virtual car installation [1], and a smaller handheld display is used by Small and Ishii to navigate virtual newspaper media and other 2D information [31]. This metaphor has also been used with video cameras on handheld devices to view the physical world with computer graphics superimposed on the display [22,24,29].…”

“…However, the Wang FreeStyle system [19] may be the first system to use voice and gesture input to capture voice and ink mark-up for documents in an annotation context. Other systems have followed similar approaches for capturing meetings [24,27]; collaborative writing [14]; video annotation [20,34]; note taking [36,37] and voicemail [13,35]. Studies of annotation in traditional media such as paper documents suggest that a free-form strategy is attractive since people show great diversity in how they annotate [23,25].…”

We introduce the Boom Chameleon, a novel input/output device consisting of a flat-panel display mounted on a tracked mechanical boom. The display acts as a physical window into 3D virtual environments, through which a one-to-one mapping between real and virtual space is preserved. The Boom Chameleon is further augmented with a touch-screen and a microphone/speaker combination. We present a 3D annotation application that exploits this unique configuration in order to simultaneously capture viewpoint, voice and gesture information. Design issues are discussed and results of an informal user study on the device and annotation software are presented. The results show that the Boom Chameleon annotation facilities have the potential to be an effective, easy to learn and operate 3D design review system.
