Detail-Preserving Variational Surface Design with Multiresolution Contraints

We present a variational framework for rapid shape prototyping. The modeled shape is represented
as a multiresolution subdivision surface which is interactively deformed by direct user input. Free-
form design goals are formulated as constraints on the shape and, following a traditional approach, the modeling problem is cast into a constrained optimization one. The focus of this paper is on handling multiresolution constraints of different kinds and on preserving surface details throughout the deformation process. We explore approximating the solution of the optimization problem to various degrees to balance trade-offs between interactivity and accuracy of the results.
