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.
- Is a complete, practical resource for programmers wishing to incorporate LOD technology into their own systems.
- Is an important reference for professionals in game development, computer animation, information visualization, real-time graphics and simulation, data capture and preview, CAD display, and virtual worlds.
- Is accessible to anyone familiar with the essentials of computer science and interactive computer graphics.
- Covers the full range of LOD methods from mesh simplification to error metrics, as well as advanced issues of human perception, temporal detail, and visual fidelity measurement.
- Includes an accompanying Web site rich in supplementary material including source code, tools, 3D models, public domain software, documentation, LOD updates, and more. Visit http://LODBook.com.

"A textbook treatment of the concepts, theories, algorithms and data structures essential for modeling detailed three-dimensional graphic worlds. The authors provide a conceptual framework for striking the tricky balance between increasing levels of detail (LOD) and the need for smooth, flowing animation. This technical reference will be of use to professionals in game development, computer animation, information visualization, and virtual reality fields." - Design Issues
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 is the founder and CEO of the software consultancy firm Code Reddy Inc. He holds a Ph.D. in Computer Science and has over 15 years of experience in the software industry. During this time, he has written 3 software patents and has published over 40 professional articles and a book on 3D computer graphics.
Dr. Reddy worked for 6 years at Pixar Animation Studios where he was lead engineer for the studio’s in-house animation system. This work involved the design and implementation of various APIs to support several Academy Award-winning and nominated films, such as "Finding Nemo", "The Incredibles", "Cars", "Ratatouille", and "Wall-E."
Dr. Reddy currently works for Linden Lab on the Second Life Viewer, an online 3D virtual world that has been used by over 16 million users around the world. His work is currently focused on a radical redesign of the Second Life Viewer, putting in place a suite of robust APIs to enable extensibility and scriptability.
