Viewpoint Selection using Viewpoint Entropy

Computation of good viewpoints is important in several fields: computational geometry, visual servoing, robot motion, graph drawing, etc. In addition, selection of good views is rapidly becoming a key issue in computer graphics due to the new techniques of Image Based Rendering. Although there is no consensus about what a good view means in Computer Graphics, the quality of a viewpoint is intui...

The Social Workers' Viewpoint

Introducing the Viewpoint

With the publication of the article by Benoit Roux and colleagues in this issue (Vargas et al.), the JGP introduces a new type of article, the Viewpoint. A Viewpoint shares features with two other article types, Perspectives and Reviews, but is distinct from them. Like the Perspective, a Viewpoint will present a summary and critical analysis of a scientific issue of strong current interest to t...

Viewpoint The Twins of

Thermal convection in a fluid layer heated from below (Rayleigh-Bénard layer) and flows between coaxial differentially rotating cylinders (Taylor-Couette system) have been investigated for more than a century, experimentally as well as theoretically. Both are attractive systems for laboratory investigations of fluid turbulence because visualizations and data gathering are easier than in experim...
