1 Using Deformation Map Painting for Bimanual, Haptic Sculpting of 3D Digital Models

We explore a novel interaction technique using force-feedback devices for creative manipulation of 3D models that combines interactive mesh deformation with painting a deformation property map. Painting a deformation map permits the artist to easily assign different values of “malle-ability ” to specific areas of the model in order to locally manipulate the deformation behavior during interactive sculpting. The technique uses Phantom force-feedback de-vices for direct 3D interactions with the 3D object and to provide the artist with immediate haptic and visual feed-back. Using a second haptic device allows us to explore complex bimanual interactions in which both hands con-tribute to the sculpting process. One example of this biman-ual interaction is painting the malleability value onto the model with one hand while simultaneously deforming it with the second hand. These complex multi-sensory interac-tions are an important step towards empowering digital 3D artists with efficient and easy-to-use 3D tools.
