dc.description.abstract	Multiresolution surfaces are especially useful for fast rendering, real-time display and interactive manipulation of large and dense terrain surface models. This paper reviews major multiresolution terrain surface reconstruction techniques and analyses the corresponding data structures. We have proposed and implemented, based on Delaunay retriangulation, a greedy refinement algorithm with a straightforward data structure to reconstruct multiresolution terrain surfaces. Our greedy refinement algorithm is a multi-pass algorithm, having the complexity of O(n 2 ) if using global error metric and O(n log n) if using local error metric.	en
