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.
