    abstract     = "In this paper, we propose the use of the Level--Set Method as the
  underlying technology of a volume sculpting system. The main
  motivation is that this leads to a very generic technique for
  deformation of volumetric solids. In addition, our method preserves
  a distance field volume representation. A scaling window is used to
  adapt the Level--Set Method to local deformations and to allow the
  user to control the intensity of the tool. Level--Set based tools
  have been implemented in an interactive sculpting system, and
  we show sculptures created using the system."
