This volume contains the research papers presented at the 12th Eurographics Workshop on Computer Animation and Simulation, Manchester, UK, September 2-3, 2001. The workshop is an international forum for research in computer-animation and simulation. This year, we choose to give a special focus on the modelling and animation of complex phenomena. This includes the modelling of virtual creature- from their body-parts to the control of their behavior, and the animation of natural phenomena such as water, smoke, fire and vegetation. The call for papers required submission of the full papers for review, and each paper was reviewed by at least 2 members of the international program committee and additional reviewers. Based on the reviews, 16 papers were accepted. We added to the final program an invited talk by Jos Stam. We wish to thank all reviewers for their time and effort in working within the rigid constraints of the tight schedule, thereby making it possible to publish this volume in time for the workshop. We also thank the authors for their contributions to the workshop, without whom this unique forum for animation and simulation work would not exist.

The 15 full and 18 short papers cover facial animation, virtual heritage and natural phenomena, virtual reality, image-based modeling and animation, database systems for animation, standards for human animation, autonomous characters and behavioral animation, digital media communication, simulating clothes, medical applications, and motion retargeting. The illustrations are monochrome and mostly screen-quality. There is no subject index. Annotation copyrighted by Book News, Inc., Portland, OR.

This volume contains the research papers presented at the Eleventh Eurographics Workshop on Computer Animation and Simulation which took place in Interlaken, Switzerland, August 21-22, 2000. The workshop is an international forum for research in human animation, physically-based modeling, motion control, animation systems, and other key aspects of animation and simulation. The call for papers required submission of the full papers for review, and each paper was reviewed by at least 3 members of the international program committee and additional reviewers. Based on the reviews, 14 papers were accepted and the authors were invited to submit a final version for the workshop. We wish to especially thank all reviewers for their time and effort in working within the rigid constraints of the tight schedule, thereby making it possible to publish this volume in time for the workshop. We also thank the authors for their contributions to the workshop, without whom this unique forum for animation and simulation work would not exist. We are grateful to the Eurographics Association and especially to Werner Purgathofer from the Technical University of Vienna, for his support in publishing the workshop as a volume of the Springer-Verlag Eurographics Series. We also thank the Eurographics '2000 organisers, especially David Duce, and Heinrich Miiller from the EG board. We are also very grateful to lerrin Celebi for the organization of the review process and and Josiane Bottarelli for the registration process.

The 20 research papers in this volume demonstrate novel models and concepts in animation and graphics simulation. Special emphasis is given on innovative approaches to Modelling Human Motion, Models of Collision Detection and Perception, Facial Animation and Communication, Specific Animation Models, Realistic Rendering for Animation, and Behavioral Animation.

The contributions to this book address the problem of synthesizing the realistic movement and behaviour of human-like characters, simulated animals, fluids, and other dynamic phenomena. The animation techniques are driven by the goals of efficiency, as required by real-time interactive animations, and quality, as demanded by animations used in feature films. This series of workshops provides a high-quality international forum for the exchange of new ideas related to the themes of character animation, simulation of dynamic natural phenomena, motion capture and analysis, physically-based modeling, behavioral animation, and visualization.

This volume contains research papers that were presented at the Sixth Eurographics Workshop on Animation and Simulation which took place at Maastricht, The Nether lands, September 2-3, 1995. A core area within computer graphics, animation is concerned with the computer synthesis of dynamic scenes. The creation of realistic animation based on the simulation of physical and biological phenomena is a unify ing and rapidly evolving research theme. This series of workshops, an activity of the Eurographics Working Group on Animation and Simulation, is an international forum where researchers representing the animation and simulation communities convene to exchange knowledge and experience related to this theme and to physics-based mod elling, human modelling, motion control, visualization, etc. Of keen interest at this sixth workshop were novel animation techniques and animation systems that simulate the dynamics and interactions of physical objects-solid, fluid, and gaseous-as well as the behaviors of living systems such as plants, lower animals, and humans. The workshop continued to promote the confluence of animation and simulation as a leading edge of computer graphics research that is providing animators with sophisticated new algorithms for synthesizing dynamic scenes. The call for extended abstracts for the workshop, issued in February 1995, elicited an enthusiastic response.
