Enhanced Visualization - Making Space for 3-D Images

Informationen zum Autor Barry G. Blundell , PhD, is a physicist and engineer who has worked in the area of 3-D display and interaction systems since the late 1980s. His research interests in the development of new forms of creative digital media are intended to advance natural and synergistic interaction with the digital world. The author is involved in promoting new technologies and techniques for distance education-particularly for use in third world countries-and also in highlighting ethical issues arising as a consequence of the deployment, networking, and accessibility of computer systems. Klappentext A comprehensive guide to the technologies and techniques used to enable computer-processed images to occupy a 3-D spaceThis authoritative book focuses on the technologies and techniques that may be used to enable computer-processed images to occupy a three-dimensional (3-D) space. Images depicted in this way take on many of the attributes that we associate with the traditional sculptured image and naturally satisfy a range of pictorial, oculomotor, and binocular depth cues, thereby avoiding depth cue conflict and viewing discomfort. In addition, this opens up exciting opportunities that exist for the development of new interaction tools and techniques.Enhanced Visualization provides a refreshing and wide-ranging insight into approaches for radically advancing our communication with the digital world.Content includes:* Discussion of a broad range of creative 3-D display system techniques* An extensive background review of volumetric systems* A chapter devoted to research undertaken in connection with varifocal systems* Identification of various types of image space* Consideration of interaction opportunities offered by different forms of image space* The impact of different display modalities upon graphics engine hardware and software* Suggestions for technologies and techniques that warrant significant research efforts* A comprehensive range of referencesA transdisciplinary approach makes the content accessible to a wide-ranging audience. This book will be of great value to undergraduate and graduate students, to researchers involved in advancing interaction with the digital world, and also to those involved in investing in new forms of computer interaction technologies.
