View-Dependent Character Animation

• Gebundenes Buch

Produktbeschreibung

Creating moving camera character animations in 3D is a multi-faceted computer graphics and computer vision problem that requires a formal representation of the moving camera, and efficient algorithms to help author manage and render the multitude of character poses required for the animation. This well-researched book introduces view-dependent character animation, covering all the relevant background work. Numerous example animations are offered to explain and illustrate this versatile technique.

Rezensionen

From the reviews:

"This book report on a view-dependent approach as a means of accomplishing this task in a reliable manner. ... Three very important appendices are provided. ... This book targets a wide audience, including both the academic research and the professional animation artist. It attempts to be self-contained ... . A number of figures are provided to help the reader understand the concepts presented. ... This book is comprehensive, and is a job well done." (R. Goldberg, Computing Reviews, January, 2008)
