Shape Forming by Cutting and Deforming Operations

In this paper, an implementation of visual and haptic feedback of deforming and cutting operations is discussed. In the implementation of the deforming operation, the surface shape is represented by a geometric model while the physical reaction is simulated using a spring model. The deformation of the spring model is reflected onto the geometric model by using the interpolation technique. In the implementation of the cutting operation, we realize visual and haptic feedback of the cutting operation remarking on the geometric and physical aspects, respectively. Combining the deforming and the cutting environment, we successfully implemented a work space in which we can form and design shapes through operations similar to clay modeling.
