This book shows how the web-based PhysGL programming environment (http://physgl.org) can be used to teach and learn elementary mechanics (physics) using simple coding exercises. The book's theme is that the lessons encountered in such a course can be used to generate physics-based animations, providing students with compelling and self-made visuals to aid their learning. Topics presented are parallel to those found in a traditional physics text, making for straightforward integration into a typical lecture-based physics course. Users will appreciate the ease at which compelling OpenGL-based graphics and animations can be produced using PhysGL, as well as its clean, simple language constructs. The author argues that coding should be a standard part of lower-division STEM courses, and provides many anecdotal experiences and observations, that include observed benefits of the coding work.

This book presents techniques for creating fluid-like animations with no required advanced physics and mathematical skills. It describes how to create fluid animations like water, smoke, fire, and explosions through computer code in a fun manner. It includes a historical background of the computation of fluids as well as concepts that drive fluid animations, and also provides computer code that readers can download and run on several platforms to create their own programs using fluid animation.

The booming computer games and animated movie industries continue to drive the graphics community's seemingly insatiable search for increased realism, believability, ad speed. To achieve the quality expected by audiences of today's games and movies, programmers need to understand and implement physics-based animation. To provide this understanding, this book is written to teach students and practitioners and theory behind the mathematical models and techniques required for physics-based animation. It does not teach the basic principles of animation, but rather how to transform theoretical techniques into practical skills. It details how the mathematical models are derived from physical and mathematical principles, and explains how these mathematical models are solved in an efficient, robust, and stable manner with a computer. This impressive and comprehensive volume covers all the issues involved in physics-based animation, including collision detection, geometry, mechanics, differential equations, matrices, quaternions, and more. There is excellent coverage of collision detection algorithms and a detailed overview of a physics system. In addition, numerous examples are provided along with detailed pseudo code for most of the algorithms. This book is ideal for students of animation, researchers in the field, and professionals working in the games and movie industries. Topics Covered: * The Kinematics: Articulated Figures, Forward and Inverse Kinematics, Motion Interpolation * Multibody Animation: Particle Systems, Continuum Models with Finite Differences, the Finite Element Method, Computational Fluid Dynamics * Collision Detection: Broad and Narrow Phase Collision Detection, Contact Determination, Bounding Volume Hierarchies, Feature-and Volume-Based Algorithms

Physics forms the basis for many of the motions and behaviors seen in both the real world and in the virtual worlds of animated films, visual effects, and computer games. By describing the underlying physical principles and then creating simulations based on these principles, these computer-generated worlds are brought to life. Physically Based Modeling and Animation goes behind the scenes of computer animation and details the mathematical and algorithmic foundations that are used to determine the behavior underlying the movement of virtual objects and materials. Dr. Donald House and Dr. John Keyser offer an approachable, hands-on view of the equations and programming that form the foundations of this field. They guide readers from the beginnings of modeling and simulation to more advanced techniques, enabling them to master what they need to know in order to understand and create their own animations Emphasizes the underlying concepts of the field, and is not tied to any particular software package, language, or API. Develops concepts in mathematics, physics, numerical methods, and software design in a highly integrated way, enhancing both motivation and understanding. Progressively develops the material over the book, starting from very basic techniques, and building on these to introduce topics of increasing complexity. Motivates the topics by tying the underlying physical and mathematical techniques directly to applications in computer animation.

In this thesis, we explore the problem of synthesizing realistic soundtracks for physicsbased computer animations. While the problem of producing realistic animations of physical phenomena has received much attention over the last few decades, comparatively little attention has been devoted to the problem of generating synchronized soundtracks for these simulations. Recent work on sound synthesis in the computer graphics community has largely focused on producing sound for simple, rigid-body animations. While these methods have been successful for certain scenes, the range of examples for which they produce convincing results is quite limited. In this thesis, we introduce a variety of new sound synthesis algorithms suitable for generating physics-based animation soundtracks. We demonstrate synthesis results on a variety of animated scenes for which prior methods are incapable of producing plausible sounds. First, we introduce a new algorithm for synthesizing sound due to nonlinear vibrations in thin shell structures. Our contributions include a new thin shell-based dimensional model reduction approach for efficiently simulating thin shell vibrations. We also provide a novel data-driven model for acoustic transfer due to vibrating objects, allowing for very fast sound synthesis once object vibrations are known. We find that this sound synthesis method produces significantly more realistic results than prior rigidbody sound synthesis algorithms for a variety of familiar objects. Next, we further address the limitations of prior sound synthesis techniques by introducing a new method for synthesizing rigid-body acceleration noise - sound produced when an object experiences rapid rigid-body acceleration. We develop an effi- cient impulse-based model for synthesizing sound due to arbitrary rigid-body accelerations and build a system for modeling plausible rigid-body accelerations due to contact events in a standard rigid-body dynamics solver. This allows us to efficiently recover acceleration sound using data readily available from rigid-body simulations. Our results demonstrate that our method significantly improves upon the results available when using traditional rigid-body sound synthesis with no acceleration noise modeling. We also introduce a scalable proxy model which provides us with a practical method for synthesizing acceleration sound from scenes with hundreds to thousands of unique objects. This allows us to produce substantially improved sound results for phenomena such as rigid-body fracture. Finally, we also consider sound from other, non-rigid phenomena; specifically, sound from physics-based animations of fire. We propose a hybrid sound synthesis algorithm combining physics-based and data-driven approaches. Our method produces plausible results for a variety of fire animations. Moreover, our use of data-driven synthesis grants users of our method a degree of artistic control.
