Abstract
A method of removing an intersection test error in ray tracing includes obtaining an intersection by performing an intersection test on a ray and a primitive; determining location information of the intersection indicating whether the intersection is located inside or outside an object; determining an intersection error based on comparing the location information of the intersection to path information of the ray.
