Abstract: A new technique is presented for computing transformations between polyhedral objects. Here, the correspondence and the interpolation problems are considered jointly. The approach gives the animator high level control of the shape transformation by providing natural specification and interaction. Keywords: Computer Animation, Computer-Aided Geometric Design, Interpolation, Deformation, Shape transformation. 1 Introduction We are interested in simulating deformations of geometric shapes. The way the deformation is specified is important: it determines both the flexibility and the usability of the deformation tool. There exists many approaches to deform a 3D shape from an object using a modelization of a time-dependent deformation process (cf. [Bar84, TPBF87, PEF + 90, CJ91, BD93]). Our goal is to provide a general and intuitive tool that computes a shape transformation mainly specified by two shapes: the initial and the final shapes. Such a tool is useful in both animation and desig...
