THE METHOD AND APPARATUS FOR PERFORMING RAY-NODE INTERSECTION TEST

摘要

Disclosed are a method and apparatus for performing a ray-node intersection test. The method of the present invention comprises the followings steps: receiving a coordinate value of a bounding box, and an origin coordinate value of a ray as a fixed point value; obtaining a difference value between the received coordinate value of the bounding box and the origin coordinate value; and obtaining a value of the obtained difference value multiplied by a reciprocal value of a direction vector of the ray, wherein the reciprocal value is a floating point value.
