Abstract [en]

In this paper, bounding volume trees of slab cut balls are evaluated and compared with other types of trees for raytracing. A novel tree construction algorithm is proposed, which utilizes a relative orientation heuristic betweenparent and child nodes. Also, a fast intersection test between a ray and a slab cut ball is presented. Experimentalcomparisons to other commonly used enclosing shapes reveal that the slab cut ball is attractive. In particular, theslab cut ball outperforms the sphere in all tested scenes with speed-up factors between 1 and 4.
