This book is the fruit of many years of experience on the creation of synthetic worldsandvirtualrealities.Ourgoalistotransmitthisexperiencetostudents and ease the learning curve required to master the creation of Virtual Reality (VR) applications. We start by providing some brief answers to key questions such as: where did VR come from? what are the main concepts that help us understand this research ?eld? what are the current VR trends? and last but not least, how can we create virtual worlds? Throughout the book we consider the terms virtual environment, v- tualworld and VRapplication asequivalentconcepts: computer-generated environments mainly composed of interactive computer graphics, designed to physically and/or psychologically immerse one or more users in an alternative reality. The ?rst part of the book makes a review of the basic theoretical and practical concepts involved in the visual aspect of virtual environments. We startbypresentingthebasicmathematicalfoundationsforthesynthesisof3D graphics, includingbasicmodelingandrenderingtechniques.Acomprehensive review of the state of the art of computer animation closes this part."
The author claims that, in our progress, in a techno-logos driven linear and literal way of dealing with reality, we are moving from a macro-cosmic sense of the reality of being to a microscopic knowledge of truth. In the "mythic" vision of reality, the ground is naturally spiritual, but in the "un-reality" that we now approach, the ground is virtually artificial, as in the new singularity and a data based reality. This is not a change in reality, but a change in the human who is becoming focused on data, technos, and mediation, rather than the essence of nature-earth as not only the unique habitat of the unique human and other beings, but the essence of reality which is manifested in the existence of life. This is the real ground of reality, but it requires relationship and experience. The usual example the author gives is that between water, as nature, and human being as an organism, and in this relationship, it can be seen that the essence of water is in the experience of drinking, not in the knowledge and ideas about water. This is a way to look at nature as essence, and life as the manifestation of that essence. In our megatrend, we are moving from this essence being the vision of reality being naturally spiritual toward reality being virtually artificial. Another way of saying this is the move from reality of being to the reality of knowing, or from a macro-cosmic reality to a microscopic truth.
Virtual reality has been a major influence in the development of information organization and management. Furthermore, it has also changed the process of designing information systems to make them more suitable for required applications. This book covers a wide range of applications of virtual reality and developments occurring in this field. The book discusses the applications of virtual reality in varied fields such as robot technology, industry and construction, and multimedia technology. This book will be beneficial for readers interested in learning more about the field of virtual reality.
Virtual Manufacturing presents a novel concept of combining human computer interfaces with virtual reality for discrete and continuous manufacturing systems. The authors address the relevant concepts of manufacturing engineering, virtual reality, and computer science and engineering, before embarking on a description of the methodology for building augmented reality for manufacturing processes and manufacturing systems. Virtual Manufacturing is centered on the description of the development of augmented reality models for a range of processes based on CNC, PLC, SCADA, mechatronics and on embedded systems. Further discussions address the use of augmented reality for developing augmented reality models to control contemporary manufacturing systems and to acquire micro- and macro-level decision parameters for managers to boost profitability of their manufacturing systems. Guiding readers through the building of their own virtual factory software, Virtual Manufacturing comes with access to online files and software that will enable readers to create a virtual factory, operate it and experiment with it. This is a valuable source of information with a useful toolkit for anyone interested in virtual manufacturing, including advanced undergraduate students, postgraduate students and researchers.
When I suffered my first seizure while asleep, I didn't know what had happened. I only knew that I felt as if I'd been run over by a Mack truck. It wasn't until later, after my quality of life had deteriorated precipitously, that I finally received a diagnosis: nocturnal epileptic seizures. They were life-threatening-and uncontrollable, even with medication. Brain surgery offered me a way out. But after surgeons at Seattle's Harborview Hospital removed my right temporal lobe and "tailored" a portion of my hippocampus, I awoke to a disorienting world in which my own face was no longer recognizable to me in the mirror. This is my story of pain, diagnosis, and recovery. My book brings forth the unseen effects TBI has on the survivor by using ananologies of what we experience. I hope it will aid others, whether patients or their supporters, as they navigate the uncertainties associated with TBI and recovery.
