Abstract
In this paper we investigate the use of morphing techniques to represent the continuous evolution of deformable moving objects, representing the evolution of real-world phenomena. Our goal is to devise processes capable of generating an approximation of the actual evolution of these objects with a known error. We study the use of different smoothing and remeshing methods and analyze various statistics to establish mesh quality metrics with respect to the quality of the approximation (interpolation). The results of the tests and the statistics that were collected suggest that the quality of the correspondence between the observations has a major influence on the quality and validity of the interpolation, and it is not trivial to compare the quality of the interpolation with respect to the actual evolution of the phenomenon being represented. The Angle-Improving Delaunay Edge-Flips method, overall, obtained the best results, but the Remeshing method seems to be more robust to abrupt changes in the geometry.
