Method and apparatus for removing false intersection in ray tracing

摘要

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.

1. A method of removing an intersection test error in ray tracing, the method comprising:
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; and determining that an intersection error has occurred in response to the location information indicating that the intersection is located at an inner surface of the object and the path information of the ray being OUT_RAY, or in response to the location information indicating that the intersection is located at an outer surface of the object and the path information of the ray being IN_RAY, wherein the IN_RAY is path information of a ray passing through the inside of the object, and the OUT_RAY is path information of a ray passing through the outside of the object.
