This paper presents a generic technique for acceleration of ray tracing of
polygonal scenes. We propose scheduling rays in a way that forms pyramidal
shafts. We show that under certain conditions fulfilled by the corner rays
of a shaft, it is possible to immediately and conservatively answer
visibility queries for the inner rays without expensive ray traversal
through acceleration data structures (kd-tree in our case). We show that
the presented technique is suitable for primary, secondary, and shadow
rays.
