This book gives an excellent overview of the problems and solutions to level-of-detail rendering. Few books in the computer graphics field are this well written.

A few things to note:

- Though there's plenty of material on simplification of polygonal meshes, there doesn't seem to be much on volume (tetrahedral) simplification. My impression is that volume simplification is kind of hairy, though, and might require its own textbook.

- If you wish to do your own level of detail rendering, you may end up reading the papers referred to in the book. Most of those papers are available online (try google).

- The terrain chapter is great, and even deals with real-world issues (geospatial file formats, terrain data on the web, what a geoid is, etc) in addition to an overview of different approaches to terrain simplification.

If you're doing level-of-detail stuff, it is basically your duty to buy this book. I only wish I'd bought it eariler.
