Haptic sculpting of dynamic surfaces

Abstract: Conventional free-form surface design usually require tedious control-point manipulation and/or painstaking constraint specification via unnatural mouse-based interfaces. This paper presents a novel haptic approach for the direct manipulation of physics-based B-spline surfaces. Our method permits users to interactively sculpt virtual yet real material with a standard haptic device, and feel the physically realistic presence of virtual B-spline objects with force feedback throughout the design process. We aim t… Show more

“…VMD communicates with the haptic device via a server [87] that controls the haptic environment experienced by the user, as described in [52]. The scheme of splitting the haptic, visualization, and simulation components into three communicating, asynchronous processes has been employed successfully [52,88] and permits all three components to run at top speed, maximizing the responsiveness of the system. IMD requires efficient network communication between the visualization front-end and the MD back-end.…”

“…Haptic rendering technologies that guide a point avatar consist of methods grounded on penalty [20] where the effect produced is in proportion with the penetration into virtual objects, and methods grounded on constraint [26,33], where the computed effect is in proportion with the shifting between the haptic interaction point (HIP) and the point of surface contact. The expansion of geometry-based methods to the haptic presentation of transformable objects has utilization in haptic sculpting [3,6] as well as CAD system [9,16]. In physics-based techniques, the computing of the interaction effects is the component of modeling based on physics.…”

“…Ye et al [27] incorporated certain functional constraints into the design process of geometric shapes. Dachille et al [28] presented a haptic approach for the direct manipulation of physics-based B-spline surfaces. In general, physics-based techniques have various applications in visual computing areas [29][30][31][32][33][34].…”
