             abstract = "Multiresolution terrain models allow the extraction of the surface 
                         at different levels of details. Real terrain data is large enough 
                         to prevent from real-time walk-through at a reasonable level of 
                         detail. Moreover, a coarse view of a terrain may not attend some 
                         application requirements. Therefore extracting the surface at 
                         variable resolution may offer impressive good-looking views if, 
                         for instance, regions closer to the observer are shown at a higher 
                         resolution then regions farther away. Besides, variable resolution 
                         extraction dramatically reduces the number of polygons to be 
                         rendered allowing real-time walk-through of a large terrain model. 
                         This paper proposes a multiresolution terrain model, based on 
                         Delaunay triangulation, that takes into account the whole domain 
                         during triangulation without replicating unchanged triangles 
                         through different levels of detail. The proposed model is the 
                         first that matches a whole domain Delaunay triangulation with 
                         accuracy of extraction and low storage cost algorithms.",
