Download or read book Computational Algorithms for Increased Control of Depth viewing Volume for Stereo Three dimensional Graphic Displays written by Steven P. Williams and published by . This book was released on 1992 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three-dimensional pictorial displays incorporating depth cues by means of stereopsis offer a potential means of presenting information in a natural way to enhance situational awareness and improve operator performance. Conventional computational techniques rely on asymptotic projection transformations and symmetric clipping to produce the stereo display. Implementation of two new computational techniques, an asymmetric clipping algorithm and a piecewise linear projection transformation, provides the display designer with more control and better utilization of the effective depth-viewing volume to allow full exploitation of stereopsis cuing. Asymmetric clipping increases the perceived field of view (FOV) for the stereopsis region. The total horizontal FOV provided by the asymmetric clipping algorithm is greater throughout the scene viewing envelope than that of the symmetric algorithm. The new piecewise linear projection transformation allows the designer to creatively partition the depth-viewing volume, with freedom to place depth cuing at the various scene distances at which emphasis is desired.

This book was released on 2020-04-20 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gathers selected papers presented at the conference “Advances in 3D Image and Graphics Representation, Analysis, Computing and Information Technology,” one of the first initiatives devoted to the problems of 3D imaging in all contemporary scientific and application areas. The aim of the conference was to establish a platform for experts to combine their efforts and share their ideas in the related areas in order to promote and accelerate future development. This second volume discusses algorithms and applications, focusing mainly on the following topics: 3D printing technologies; naked, dynamic and auxiliary 3D displays; VR/AR/MR devices; VR camera technologies; microprocessors for 3D data processing; advanced 3D computing systems; 3D data-storage technologies; 3D data networks and technologies; 3D data intelligent processing; 3D data cryptography and security; 3D visual quality estimation and measurement; and 3D decision support and information systems.

Download or read book Virtual Environments and Advanced Interface Design written by Woodrow Barfield and published by Oxford University Press. This book was released on 1995-06-01 with total page 595 pages. Available in PDF, EPUB and Kindle. Book excerpt: This sweeping introduction to the science of virtual environment technology masterfully integrates research and practical applications culled from a range of disciplines, including psychology, engineering, and computer science. With contributions from the field's foremost researchers and theorists, the book focuses in particular on how virtual technology and interface design can better accommodate human cognitive, motor, and perceptual capabilities. Throughout, it brings the reader up-to-date with the latest design strategies and cutting-edge virtual environments, and points to promising avenues for future development. The book is divided into three parts. The first part introduces the reader to the subject by defining basic terms, identifying key components of the virtual environment, and reviewing the origins and elements of virtual environments. The second part focuses of current technologies used to present visual, auditory, tactile, and kinesthetic information. The book concludes with an in-depth analysis of how environments and human perception are integrated to create effective virtual systems. Comprehensive and splendidly written, Virtual Environments and Advanced Interface Design will be the "bible" on the subject for years to come. Students and researchers in computer science, psychology, and cognitive science will all want to have a copy on their shelves.
