Computing simple paths among obstacles
Given a set X of points in the plane, two distinguished points s,t X, and a set of obstacles represented by line segments, we wish to compute a simple polygonal path from s to t...

Fast and accurate collision detection for haptic interaction using a three degree-of-freedom force-feedback device
We present a fast and accurate collision detection algorithm for haptic interaction with polygonal models. Given a model, we pre-compute a hybrid hierarchical representation, cons...
