Available in PDF, EPUB and Kindle. Book excerpt: A configuration of an articulated figure of joints and segments can sometimes be specified as spatial constraints. Constrained parts on the articulated figure are abstracted as end effectors, and the counterparts in the space are abstracted as goals. The goal (constraint) can be as simple as a position, an orientation, a weighted combination of position and orientation, a line, a plane, a direction, and so on, or it could be as complicated as a region in the space. An articulated figure consists of various segments connected together by joints has some degrees of freedom which are subject to joint limits and manual adjustment. This paper presents an efficient algorithm to adjust the joint angles subject to joint limits so that the set of end effectors concurrently attempt to achieve their respective goals. Users specify end effectors and goals: the program computes a final configuration in real time in the sense that actions appear to take no longer than actual physical activities would. If it is impossible to satisfy all the goals owing to the actual constraints, the program should end up with the best possibility according to the user's assignment of importances to each goal. (kr).

Available in PDF, EPUB and Kindle. Book excerpt: During the past decade, high-performance computer graphics have found application in an exciting and expanding range of new domains. Among the most dramatic developments has been the incorporation of real-time interactive manipulation and display for human figures. Though actively pursued by several research groups, the problem of providing a synthetic or surrogate human for engineers and designers already familiar with computer-aided design techniques was most comprehensively solved by Norman Badler's computer graphics laboratory at the University of Pennsylvania. The breadth of that effort as well as the details of its methodology and software environment are presented in this volume. The book is intended for human factors engineers interested in understanding how a computer-graphics surrogate human can augment their analyses of designed environments. It will also inform design engineers of the state of the art in human figure modeling, and hence of the human-centered design central to the emergent concept of concurrent engineering. In fulfilling these goals, the book additionally documents for the entire computer graphics community a major research effort in the interactive control of articulated human figures.

This book was released on 2003-05-20 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: The CAPTECH'98 workshop took place at the University of Geneva on November 26–27, 1998, sponsored by FIP Working Group 5.10 (Computer Graphics and Virtual Worlds) and the Suisse Romande regional doctoral seminar in computer science. The subject of the conference was ongoing research in data capture and interpretation. The goals of capturing real world data in order to perceive, understand, and interpret them and then reacting to them in a suitable way are currently important research problems. These data can be very diverse: sounds, emotions, shapes, motions, forces, muscles, actions, etc. Once captured, they have to be treated either to make the invisible visible, or to understand a particular phenomenon so as to formulate an appropriate reaction, or to integrate various information in a new multimedia format. The conference included six sessions of presented papers and three panel discussions. Invited speakers treating various aspects of the topic were: Professor R. Earnshaw from Bradford University, Professor T. L. Kunii from Hosei University, and Professor P. Robert from EPFL. Professor K. Bauknecht, of the University of Zürich, President of IFIP, offered the welcoming address. Mr. E. Badique, project officer for the EU in Brussels, discussed recent results of the EU ACTS research program. Finally, the Geneva Computer Animation '98 Film Festival highlighted the evening of November 26.

Download or read book Making Them Move written by Norman I. Badler and published by Taylor & Francis. This book was released on 2017-09-08 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current computer graphics hardware and software make it possible to synthesize near photo-realistic images, but the simulation of natural-looking motion of articulated figures remains a difficult and challenging task. Skillfully rendered animation of humans, animals, and robots can delight and move us, but simulating their realistic motion holds great promise for many other applications as well, including ergonomic engineering design, clinical diagnosis of pathological movements, rehabilitation therapy, and biomechanics. Making Them Move presents the work of leading researchers in computer graphics, psychology, robotics and mechanical engineering who were invited to attend the Workshop on the Mechanics, Control and Animation of Articulated Figures held at the MIT Media Lab in April 1989. The book explores biological and robotic motor control, as well as state-of-the-art computer graphics techniques for simulating human and animal figures in a natural and physically realistic manner.

Available in PDF, EPUB and Kindle. Book excerpt: The very word "digital" has acquired a status that far exceeds its humble dictionary definition. Even the prefix digital, when associ ated with familiar sectors such as radio, television, photography and telecommunications, has reinvented these industries, and provided a unique opportunity to refresh them with new start-up companies, equipment, personnel, training and working practices - all of which are vital to modern national and international economies. The last century was a period in which new media stimulated new job opportunities, and in many cases created totally new sectors: video competed with film, CDs transformed LPs, and computer graphics threatened traditional graphic design sectors. Today, even the need for a physical medium is in question. The virtual digital domain allows the capture, processing, transmission, storage, retrieval and display of text, images, audio and animation without familiar materials such as paper, celluloid, magnetic tape and plastic. But moving from these media to the digital domain intro duces all sorts of problems, such as the conversion of analog archives, multimedia databases, content-based retrieval and the design of new content that exploits the benefits offered by digital systems. It is this issue of digital content creation that we address in this book. Authors from around the world were invited to comment on different aspects of digital content creation, and their contributions form the 23 chapters of this volume.

Available in PDF, EPUB and Kindle. Book excerpt: Caves have been used in various ways across human society, but despite the persistence within popular culture of the iconic caveman, deep caves were never used primarily as habitation sites for early humans. Rather, in both ancient and contemporary contexts, caves have served primarily as ritual spaces. In Sacred Darkness, contributors use archaeological evidence as well as ethnographic studies of modern ritual practices to envision the cave as place of spiritual and ideological power that emerges as a potent venue for ritual practice. Covering the ritual use of caves in Europe, Asia, Australia, Africa, Mesoamerica, and the US Southwest and Eastern woodlands, this book brings together case studies by prominent scholars whose research spans from the Paleolithic period to the present day. These contributions demonstrate that cave sites are as fruitful as surface contexts in promoting the understanding of both ancient and modern religious beliefs and practices. This state-of-the-art survey of ritual cave use will be one of the most valuable resources for understanding the role of caves in studies of religion, sacred landscape, or cosmology and a must-read for any archaeologist interested in caves.
