Summary

During the simulation of subtractive manufacturing processes the real-time generation of exact swept volumes is essential. While low quality approximations have been available for some time, the just-in-time reconstruction of high quality swept volumes has not been possible until recently due to the high computational costs of such an approach. A point cloud based approach is presented in this paper, which has no limitations regarding complexities of the tool geometry and the tool trajectory. The main contribution of the paper is a parallel implementation of the ball pivoting algorithm (BPA) for surface reconstruction. For a given point cloud with uniform point density the algorithm constructs a water-tight surface. Because of its high triangle throughput and good scalability, it is a well-fitting method for high quality swept volume computation in real-time.
