Shape and material property modeling with haptic interaction

Rapid development of data acquisition technology like 3D scanner makes it possible to obtain geometry information of highly complex objects at high speed and with good accuracy. For the realistic haptic interaction with these objects, we propose an interactive efficient haptic reshaping and material property modeling. The proposed modeling supports not only a physically-based reshaping of very complex objects such as a real human face captured from 3D scanner but also efficient modeling of material properties such as roughness, stiffness, and friction.
