This monograph originates from my work on the HAPTEX project. In - cember 2004 Prof. Franz-Erich Wolter, the head of the Institute of Man- Machine Communication of the Leibniz Universit. at Hannover, o?ered me the opportunity to participate in that EU funded project. Being a mat- matician I had only very little experience in the ?eld of haptic simulation in those days, but Prof. Wolter trusted in my ability to become acquainted with new ?elds of research in a very short time. I am still thankful for the con?dence he has shown me. Since then I indeed learned and found out a lot. With this monograph I try to pass on the knowledge I gained. Having a reader in mind who-like me at the beginning of the project-has no background in psychophysics, neurophysiologyortextileengineeringIwillprovidethenecessarybasics.The skilled reader may safely skip these parts. Nevertheless I presume some basic knowledge in mathematics. I hope that this thesis might help a newcomer to discover the fascinating ?eld of tactile simulation. This workwouldnot havebeen possible without the funding of the project "HAPtic sensing of virtual TEXtiles" (HAPTEX) under the Sixth Fra- work Programme (FP6) of the European Union (Contract No. IST-6549).
Augmented (AR) and Virtual Reality (VR) technologies are increasingly being used in manufacturing processes. These use real and simulated objects to create a simulated environment that can be used to enhance the design and manufacturing processes.
Virtual Reality and Augmented Reality Applications in Manufacturing is written by experts from the world s leading institutions working in virtual manufacturing and gives the state of the art of the field.
- Chapters covering the state of the art in VR and AR technology and how these technologies can be applied to manufacturing.
- The latest findings in key areas of AR and VR application to manufacturing.
- The results of recent cross-disciplinary research projects in the US and Europe showing application solutions of AR and VR technology in real industrial settings.
Virtual Reality and Augmented Reality Applications in Manufacturing will be of interest to all engineers wishing to keep up-to-date with technologies that have the potential to revolutionize manufacturing processes over the next few years."
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 book presents a history of classical mechanics by focusing on issues of equilibrium. The historical point of view adopted here restricts attention to cases where the effectiveness of forces is assessed on the basis of the virtual motion of their points of application. For completeness, hints of the alternative approach are also referred, the Archimedean for ancient mechanics and the Newtonian for modern mechanics. The laws resulting from consideration of virtual motions are named laws of virtual work. The modern formulations of the principle of virtual work are only a particular form of them.
The book begins with the first documented formulations of laws of virtual work in the IV century BC in Greece and proceeds to the end of the XIX century AD in Europe. A significant space is devoted to Arabic and Latin mechanics of Middle Ages. With the Renaissance it began to appear slightly different wordings of the laws, which were often proposed as unique principles of statics. The process reached its apex with Bernoulli and Lagrange in the XVIII century. The book ends with some chapters dealing with the discussions that took place in the French school on the role of the Lagrangian version of the law of virtual work and its applications to continuum mechanics.
Our Paranormal Reality, a True Haunting. Book 1, The Early Years, Is the actual story of a family dealing with an evil entity. What was first only a nuisance, quickly turns into a haunting of the worst kind. When demonic forces threaten to destroy this family, they begin to fight back. They enter into a battle for their home, their family and their very lives.
