This paper presents techniques for speeding up commonly used algorithms for bounding volume construction using Intel’s SIMD SSE instructions. A case study is presented; which shows that speed-ups between 7–9 can be reached in the computation of k-DOPs. For the computation of tight fitting spheres; a speed-up factor of approximately 4
is obtained. In addition; it is shown how multi-core CPUs can be used to speed up the algorithms further.
