July/August 2007 Published by the IEEE Computer Society 0272-1716/07/$25.00 © 2007 IEEE Clean, Green 3D Printing Z Corporation—the only maker of multicolor 3D printers—announced the release of zp140, a highperformance composite material that reportedly introduces the world’s easiest, safest, and greenest postprocessing option for finishing monochrome 3D printed models. Using a quick mist with t...

The colourful simplicial depth (CSD) of a point x ∈ R relative to a configuration P = (P , P , . . . , P ) of n points in k colour classes is exactly the number of closed simplices (triangles) with vertices from 3 different colour classes that contain x in their convex hull. We consider the problems of efficiently computing the colourful simplicial depth of a point x, and of finding a point in ...

Display systems based on conventional computer graphics cards are capable of generating images with about 8-bit luminance resolution. However, most vision experiments require more than 12 bits of luminance resolution. Pelli and Zhang [Spatial Vis. 10 (1997) 443] described a video attenuator for generating high luminance resolution displays on a monochrome monitor, or for driving just the green ...

Qualitative longitudinal research (QLR) has grown in prominence and popularity since the 2007 themed section on subject this journal. This new reflects how QLR been mobilised made sense of recent times. article showcases QLR’s distinctive way knowing understanding social world it can illuminate processes through which policy enhance, or indeed inhibit, well-being individuals groups within socie...

Painted turtles (Chrysemys picta) are commercially harvested in large numbers in Minnesota for sale to biological supply companies and the pet trade. We investigated the possible effects of this harvest by comparing size, demography, and catch rates of painted turtles in 12 harvested and 10 nonharvested painted turtle populations in 2001 and 2002. We correlated turtle catch rates to harvest sta...

This paper describes an ongoing project to digitally record, reconstruct and repaint a 2000-year-old painted Roman statue from Herculaneum, Italy. The paper considers the archaeological potential for extremely detailed laser scanning and digital recreation of Roman statuary, and visualisation within a physically accurate context. It focuses on the archaeological significance of the emerging tec...

Photographers often wish to control the depth of field. In particular, for portrait photography, a shallow depth of field can have dramatic effects on the composition and the feel of the picture. For example, a shallow depth of field can help direct attention to the subject by blurring out objects too close or too far from the camera, such as distracting objects or faces. Also, focusing on an o...
