abstract = "Many 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.",
