In technological terms, the development of a Web site for an online community presents unique challenges principally in terms of managing the interactions among users, and between users and the company. Only through efficient management of these interactions is it possible to overcome the problems arising from the trade-off between the number of members in the community and the standards of quality for the services offered. In this paper we present WebTool, an instrument we developed to support the management of a Web community -GirLand -having a large and very cohesive membership, with the consequent need to manage the growing number of interactions among them.

When precise depth judgements need to be made these differences may become critical to task performance. Applications where this is a particular issue include medical imaging, geoscience and scientific visualization.

Aimed at a general audience for the Royal Society's 2005 Summer Science Exhibition, the movie illustrates how the latest cosmological theories based on dark matter and dark energy are capable of producing structures as complex as spiral galaxies and allows the viewer to directly compare observations from the real universe with theoretical results. 3D is an inherent feature of the cosmology data sets and stereoscopic visualization provides a natural way to present the images to the viewer, in addition to allowing researchers to visualize these vast, complex data sets. The presentation of the movie used passive, linearly polarized projection onto a 2m wide screen but it was also required to playback on a Sharp RD3D display and in anaglyph projection at venues without dedicated stereoscopic display equipment. Additionally lenticular prints were made from key images in the movie. We discuss the following technical challenges during the stereoscopic production process; 1) Controlling the depth presentation, 2) Editing the stereoscopic sequences, 3) Generating compressed movies in display specific formats. We conclude that the generation of high quality stereoscopic movie content using desktop tools and equipment is feasible. This does require careful quality control and manual intervention but we believe these overheads are worthwhile when presenting inherently 3D data as the result is significantly increased impact and better understanding of complex 3D scenes.

Our study is motivated by the increasing use of 3D displays in applications, including geo-science and medicine, where critical decisions are made using fine binocular depth judgements. We predict subject performance for a depth judgement task using published specifications for seven different 3D displays. A repeated measures, within subjects experimental design is used to determine the effect that display and binocular disparity have on subject scores in the task. We find that there is reliable variation in participant performance with display and disparity, however this variation is not always consistent with our predictions from the display specifications. We also present subjective results that suggest user preference for a 3D display is not always a reliable guide to their ability to perform the task. We conclude that care must be taken in selecting 3D display systems for tasks that critically rely on human depth judgement.

To account for this our Three Region stereoscopic camera model is able to control the depth mapping from scene to ...

Typical examples of such data sources are X-ray diffraction techniques, NMR techniques or quantum mechanic calculations. The obtained 3D data as electron density maps or atom positions are complex objects and they require sophisticated methods of visualization. In the first part of this article we will discus several data interpretation problems for which the stereoscopic visualization is strongly ...
