Validation and verification of visualization products is an integral part of the visualization process. This paper focuses on measurements and techniques for comparing the quality of meshes produced by (a) different hierarchical multiresolution (HMR) methods and (b) different levels of detail for a given multiresolution method. The main contribution from such techniques is a better understanding of the quality of competing HMR approaches, and the location and degree of degradation as one goes to a coarser or denser representation. We report on a number of statistics for comparing different surface meshes and how these may be visually presented in a number of insightful ways.
