Adaptive level of detail rendering estimation based on wavelet transform

The goal the following paper is to point out an alternative approach to the adaptive triangulation problem. A new technique of terrain rendering which uses wavelet transform to select appropriate LOD is described. This technique is a region-based multi-resolution approach that partitions the terrain into tiles that can be processed independently. The wavelet transform is used as a mathematical framework which localizes rough surface approximation where approximation error has to be controlled. It permits to choose the appropriate resolution according to local characteristics of the examined surface.
