Abstract:
The swept volume of a moving solid provides an excellent aid for path and accessibility planning
in robotics and for simulating various manufacturing operations. To compute the boundary of the
swept volume, we approximate the motion by a polyscrew (continuous, piecewise-screw), generate
candidate faces, compute the two-cells of their arrangement, and use a new point-in-sweep test
to select the correct cells whose union forms the boundary of the swept volume.
