Paper Abstract:	In this paper, we describe a small-scale virtual reality system to support the creative manipulation of digital models (meshes) in 3D via two Phantom force-feedback devices. The system permits the artist to interact with a 3D model with both hands simultaneously and to view and feel the model in a 3D virtual environment. The system supports the application of color through painting, cutting and sculpting through interactive deformation of the 3D models in real-time with immediate visual and haptic (force) feedback. A 3D model's deformation properties can be altered as part of the artistic process. The main technical contributions are the bimanual (two handed) artistic interaction and a novel method for interactively defining the deformation properties ("malleability") via painting part of the 3D model with a special "deformation color.” This permits the artist to assign different values of “malleability” to specific areas of the model in order to locally manipulate the deformation behavior before or during interactive sculpting.
