Intersection Testing in a Ray Tracing System Using Axis-Aligned Box Coordinate Components

Abstract: a ray tracing system determines whether a ray intersects a three-dimensional axis-aligned box by determining whether a minimum distance condition and a maximum distance condition are satisfied, wherein the determining comprises determining whether a single distance condition is satisfied. the determination is used to determine whether the ray intersects the axis-aligned box. a point on the ray is at a position o+dt where o is a vector which represents an origin of the ray, and t represents a distance along the ray from the origin of the ray, and wherein d is a 3d vector defining a direction vector of the ray.
