Real-Time Generation of Continuous Levels of Detail for Height Fields
1998 - S. Röttger, W. Heidrich, Ph. Slusallek, H.-P. Seidel
This paper shows how to do continuous level of detail using geomorphing on heightfields. Basic datastructure structure used is a quadtree extracted from the heightmap without any extra memory used. A Real-Time Procedural Universe, Part 2: Rendering Planetary Bodies
