shape interpolation
boundary representation
AbstractMany aproaches have been proposed to generate a shape interpolation, or morphing, of polyhedral objects in a facet based representation. Most of them focus only the correspondence problem, leaving the interpolation process to just a corresponding vertices interpolation. In this paper we present a variation for the 3-dimension space of the technic used in [Oliv96], that uses TFDs (Fields of Directions defined in a Triangulation). Our algorithm is based on a field of vectors defined in a constrained tetrahedralization of the space between the two objects to be interpolated, after having placed one inside the other. The algorithm guarantees to generate homeomorphisms and a topology preserving continuous transformation process between the models. Examples of such transformations involving simple models are presented to ilustrate the approach.
