Do You Have to See Everything - All the Time? Or is it at All Possible?

Abstract

This presentation motivates the use of View Dependent Level-of-detail (LOD) in complex graphical displays, both for reducing computer workload and improving visual quality. In addition, some challenges are discussed. When generating perspective views of geographical data the resulting image can be seen as a map with a very flexible "scale". Areas near the viewer require a high data density, while areas in the background can be shown with very simplified graphics. Using data with only one single detail level gives the view some "myopia" and restricts the possibilities for giving overview presentations. LOD methods on the other hand support several "scales" in the same data model.
