According to the property of DEM,on the base of multi-resolution analysisalgorithm this paper presents a method for multi-resolution modeling based on wavelet *** the paper analyzes the principles for choosing the fittest wavelet function and boundary extension *** paper also provide a way to choose the best resolution depended on the viewpoint and the viewing angle The paper suggests to control the threshold to build data *** some experiments,this method is proved to be efficient and robustness.
