The evolving functionality and growing complexity of graphics algorithms and systems make it more difficult for the application programmer to exploit them fully. Conventional programming methods are no longer suited and new programming paradigms and system architectures are required. This book presents results from the Fourth Eurographics Workshop on Object-Oriented Graphics. Part 1, Object-Oriented Design and Systems, shows that object-oriented graphics now uses complex algorithms and systems, such as elaborate renderers, animation, and multimedia systems, that are realized as object-oriented libraries. Part 2, Programming Paradigms for Graphics, reflects upon and analyzes problems arising from relying completely on object orientation, and proposes mixed programming paradigms that may enrich object-oriented languages.
