Abstract:
A new tracing algorithm is described that supports haptic rendering of
NURBS surfaces without the use of any intermediate representation. By
using this tracing algorithm in conjunction with algorithms for
surface proximity testing and surface transitions, a complete haptic
rendering system for sculptured models has been developed. The system
links an advanced CAD modeling system with a Sarcos force-reflecting
exo-skeleton arm. A method for measuring the quality of the tracking
component of the haptic rendering separately from the haptic device
and force computation is also described.
