Abstract

A ray tracing apparatus includes a traversal (TRV) core configured to traverse an acceleration structure (AS) to detect a first node and a second node, which intersect with a generated ray and have a determined same parent node, and to determine whether the ray intersects with an overlap region where a first bounding box corresponding to the first node overlaps a second bounding box corresponding to the second node; and, an intersection test (IST) determiner configured to calculate a first hit point where the ray intersects with a primitive belonging to the first node, which is a closer node to a view point of the ray among the first node and the second node, and to determine a final hit point of the ray based on a result of the determining of whether the ray intersects with respect to an overlap region, by the TRV core.
