Ciampalini A., Cignoni P., Montani C., Scopigno R. Multiresolution decimation based on global error. In: The Visual computer, vol. 13 (5) pp. 228 - 246. Springer, 1997.
Due to surface meshes being produced at increasing complexity in many applications, interest in e¦cient simplification algorithms and multiresolution representation is very high. An enhanced simpliŞcation approach and a general multiresolution data scheme are presented here. JADE, a new simpliŞcation solution based on the mesh decimation approach, has been designed to provide both increased approximation precision, based on global error management, and multiresolution output. Moreover, we show that with a small increase in memory, which is needed to store the multiresolution data representation, we are able to extract any level of detail representation from the simpliŞcation results in an extremely e¦cient way. Results are reported on empirical time complexity, approximation quality, and simplification power.
