Gross M., Pfister H. (eds.) Point-Based Graphics
Издательство Morgan Kaufmann, 2007, -553 pp.

In any established field, doing something different presents a challenge. Even in computer graphics, an area that evolves rapidly, the notion of treating simple points as primitive modeling and display elements did not get off to a fast start.Nevertheless, every good idea has its time. Two timely factors that promote the idea of point-based graphics are procedural shape definition and automated shape acquisition. The former has the flexibility to produce as many or as few points as needed to accurately represent itself. The latter naturally produces a massive flood of points. The sheer complexity of such models begs for a representation that is inherently simple. Points are simple. However, effectively acquiring, editing, animating, rendering, and otherwise processing points requires a non-intuitive understanding of the representations and processes. That’s why this book is necessary.
Twenty years ago, when my students were experimenting with point-based representations of surfaces and volumes, they repeatedly asked what would happen if we tried this crazy idea? As demonstrated in this text, today’s discussions are conducted with more rigor and sophistication. While points themselves may be simple, a complete understanding of how they are processed and how collections of them should be interpreted requires sophisticated explanations. And there is no single best method for processing such point collections. The explanations in this book are broad; the authors cover a range of applications and techniques, and they cover these thoroughly.
The approaches described in this book may once have been considered outside the mainstreambyexperiencedgraphicspractitioners.Theeditorsandcontributorsthemselves, however, are among the best and brightest in mainstream computer graphics research. To bring their expertise to bear on a single coherent volume is no small feat.
There are undoubtedly a few of us that enjoy ideas just because of their inherent beauty. Having migrated to computer graphics from a background in signal processing, I have a certain attachment to point-based graphics methods. Because of this interest, I have tracked the work of many of the book’s contributors for several years. Their perseverance and ingenuity are an inspiration. Seeing their work collected in one place is a tremendous personal pleasure. More importantly for the reader, this text is a unique and valuable resource for those who wish to understand and make use of point-based graphics technology.
