Guide To Dynamic Simulations Of Rigid Bodies And Particle Systems

This book introduces the techniques needed to produce realistic simulations and animations of particle and rigid-body systems. The text focuses on both the theoretical and practical aspects of developing and implementing physically based dynamic-simulation engines. Each chapter examines numerous algorithms, describing their design and analysis in an accessible manner, without sacrificing depth of coverage or mathematical rigor. Features: examines the problem of computing an hierarchical representation of the geometric description of each simulated object, as well as the simulated world; discusses the use of discrete and continuous collision detection to handle thin or fast-moving objects; describes the computational techniques needed for determining all impulsive and contact forces between bodies with multiple simultaneous collisions and contacts; presents techniques that can be used to dynamically simulate articulated rigid bodies; concludes each chapter with exercises.

Sea Ice Image Processing with MATLAB addresses the topic of image processing for the extraction of key sea ice characteristics from digital photography, which is of great relevance for Artic remote sensing and marine operations. This valuable guide provides tools for quantifying the ice environment that needs to be identified and reproduced for such testing. This includes fit-for-purpose studies of existing vessels, new-build conceptual design and detailed engineering design studies for new developments, and studies of demanding marine operations involving multiple vessels and operational scenarios in sea ice. A major contribution of this work is the development of automated computer algorithms for efficient image analysis. These are used to process individual sea-ice images and video streams of images to extract parameters such as ice floe size distribution, and ice types. Readers are supplied with Matlab source codes of the algorithms for the image processing methods discussed in the book made available as online material. Features Presents the first systematic work using image processing techniques to identify ice floe size distribution from aerial images Helps identify individual ice floe and obtain floe size distributions for Arctic offshore operations and transportation Explains specific algorithms that can be combined to solve various problems during polar sea ice investigations Includes MATLAB® codes useful not only for academics, but for ice engineers and scientists to develop tools applicable in different areas such as sustainable arctic marine and coastal technology research Provides image processing techniques applicable to other fields like biomedicine, material science, etc

The Filmmaker’s Guide to Visual Effects offers a practical, detailed guide to visual effects for non-VFX specialists working in film and television. In contemporary filmmaking and television production, visual effects are used extensively in a wide variety of genres and formats to contribute to visual storytelling, help deal with production limitations, and reduce budget costs. Yet for many directors, producers, editors, and cinematographers, visual effects remain an often misunderstood aspect of media production. In this book, award-winning VFX supervisor and instructor Eran Dinur introduces readers to visual effects from the filmmaker’s perspective, providing a comprehensive guide to conceiving, designing, budgeting, planning, shooting, and reviewing VFX, from pre-production through post-production. The book will help readers: Learn what it takes for editors, cinematographers, directors, producers, gaffers, and other filmmakers to work more effectively with the visual effects team during pre-production, on the set and in post, use visual effects as a narrative aid, reduce production costs, and solve problems on location; Achieve a deeper understanding of 3D, 2D, and 2.5D workflows; the various VFX crafts from matchmove to compositing; essential concepts like photorealism, parallax, roto, and extraction; become familiar with the most common types of VFX, their role in filmmaking, and learn how to plan effectively for the cost and complexity of VFX shots; See visual effects concepts brought to life in practical, highly illustrated examples drawn from the real-world experiences of industry professionals, and discover how to better integrate visual effects into your own projects.

This book presents the results of the IUTAM Symposium on Physics and Mechanics of Sea Ice which brought together researchers who have made significant contributions in the study of sea ice. The topics include: Fracture of ice, Thermodynamics of sea ice ridges, Global and local ice loads on ships and marine structures, Computational ice engineering and ice mechanics; and Physical and engineering problems related to ice and waves.

This book introduces the techniques needed to produce realistic simulations and animations of particle and rigid body systems. It focuses on both the theoretical and practical aspects of developing and implementing physically based dynamic simulation engines that can be used to generate convincing animations of physical events involving particles and rigid bodies. It can also be used to produce accurate simulations of mechanical systems, such as a robotic parts feeder. The book is intended for researchers in computer graphics, computer animation, computer-aided mechanical design and modeling software developers.
