Abstract
An implementation comprises traversing a bounding volume hierarchy for each ray of a plurality of rays concurrently using a plurality of execution items. In response to determining that a first execution item of the plurality of execution items is finished traversing the bounding volume hierarchy for a first ray of the plurality rays, the embodiment causes the first execution item to traverse the bounding volume hierarchy for a second ray of the plurality of rays while a second execution item of the plurality of execution items traverses the bounding volume hierarchy for the second ray. And the embodiment comprises initiating side-effects with the first and second execution items in an order indicated by the bounding volume hierarchy.
