标题: Fast Multiresolution Terrain Rendering with Symmetric Cluster Sets
1 Batch Quadtree Terrain

The technique we present here improves upon a popular terrain

level-of-detail algorithm which renders using a quadtree of fixedresolution

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].

In the traditional version, a block is a single batch; each accounts

for exactly one draw call. During rendering, a top-down traversal is

used where each block node is recursively subdivided (Figure 1) to

satisfy a screen-space error metric [Urlich 2002]. As one can see,

the granularity of the resulting triangular refinement is determined

by the depth of subdivision at a given point.
