Abstract
A method of traversing an acceleration structure (AS) in a ray tracing system includes obtaining information about child nodes of a target node included in the AS; determining whether each of the child nodes intersects a ray based on the obtained information; determining a next target node among at least one child node that intersects the ray; and performing an operation corresponding to a type of the determined next target node.
