The technique we present here improves upon a popular terrain level-of-detail algorithm which renders using a quadtree of fixed-resolution mesh blocks [Strugar 2009], Our approach retains the flexibility of this method while improving its geometric batch efficiency, enabling performance more competitive to specialized techniques such as [Cignoni et al. 2003] and [Losasso and Hoppe 2004].
