Organic Shape Modeling through Haptic Devices

This paper presents a sketching system for 3D organic shapes modeling and animation using virtual reality devices. On the hardware side, it is based on the Haptic Workstation™ which conveys force feedback on the user arms (upper body limbs), and a head mounted display to present the 3D generated images. On the software side, we use implicit surfaces modeling techniques such as metaballs. In fact, designers feel well comfortable with this kind of primitives due to their ability in the organic shapes creation such as virtual humans. The proposed system provides an efficient alternative to produce advanced 3D shapes sketching
