Summary

The book is written for professionals, students, and laymen interested in virtual clothing. It contains annexes on clothing research projects and commercial clothing systems and comes with a CD-ROM providing software tools for making 3D clothes and fashion shows. Starting with the beginnings in the mid 1980s and the basic foundations from the field of mechanics, the reader is gradually introduced to the state of the art in the interdisciplinary area of virtual clothing. Relevant issues from areas such as computer graphics, algorithmics, computational geometry, simulation, modeling, animation, visualization, and virtual reality are addressed in appropriate depth and detail. Throughout the book, the MIRACloth system developed at the authors' laboratory in Geneva for simulating clothes and clothing virtual actors is used as a case study for the results and techniques developed.
