pp: 72-79
ABSTRACT
<p>A modified formulation of oriented boxing called oriented slab boxing is presented. It almost doubles the speed of the oriented boxing component in B-spline intersection. The method used to accelerate B-spline intersection includes algorithmic improvements and parallelization of the algorithm at different levels of granularity to find an optimum solution on a network of parallel processors. The software testbed is linked to a B-spline-based library, which is a prototype of what may be used in an actual engineering design environment. A parallel implementation of the algorithm on a network of three processors achieves an additional twofold improvement in speed.</p>
