Level of detail (LOD) techniques are increasingly used by professional real-time developers to strike the balance between breathtaking virtual worlds and smooth, flowing animation. Level of Detail for 3D Graphics brings together, for the first time, the mechanisms, principles, practices, and theory needed by every graphics developer seeking to apply LOD methods. Continuing advances in level of detail management have brought this powerful technology to the forefront of 3D graphics optimization research. This book, written by the very researchers and developers who have built LOD technology, is both a state-of-the-art chronicle of LOD advances and a practical sourcebook, which will enable graphics developers from all disciplines to apply these formidable techniques to their own work.
David Luebke
David is an Assistant Professor in the Department of Computer Science at the University of Virginia. His principal research interest is the problem of rendering very complex scenes at interactive rates. His research focuses on software techniques such as polygonal simplification and occlusion culling to reduce the complexity of such scenes to manageable levels. Luebke's dissertation research, summarized in a SIGGRAPH '97 paper, introduced a dynamic, view-dependent approach to polygonal simplification for interactive rendering of extremely complex CAD models. He earned his Ph.D. at the University of North Carolina, and his Bachelors degree at the Colorado College.
Dr. Martin Reddy holds a Ph.D. in Computer Science and has over 30 years of experience in the software industry. He is a Fellow of the IEEE, a Fellow of the AAIA, and a Distinguished Member of the ACM. He has published 10 patents, over 40 professional articles, and 2 books. Martin was co-founder and CTO of the AI startup, PullString, where he oversaw the development of the company's technology until it was acquired by Apple in 2019. While at Apple, Martin was a software architect responsible for the architecture and APIs of major components of the Siri virtual assistant. Before that, Dr. Reddy worked for 6 years at Pixar Animation Studios where he was a lead engineer for the studio's in-house animation system. He worked on several Academy Award Winning and Nominated films, such as "Finding Nemo", "The Incredibles", "Cars", "Ratatouille", and "Wall-E". He was also the hair model for Mr Incredible. Martin began his career at SRI International where he worked on a distributed 3D terrain visualization system and co-authored the geospatial functionality in the VRML and X3D ISO standards. Martin was awarded Alumnus of the Year by his alma mater, Strathclyde University.
