Detailed Description

Class to store the intersection of a Ray and an Object.

The fundamental operation in ray-tracing is intersecting a Ray with an Object. A RayIntersection stores the information about this intersection. As well as the Point at which the intersection occurs, the Normal to the object at that location, the Material of the object, and the distance along the ray are all required.

RayInteresections can also be sorted on distance along the ray.

Member Function Documentation

◆ operator<()

bool RayIntersection::operator< ( const RayIntersection & ri )

inline

Less-than comparison for RayIntersection.

In order to sort RayIntersection objects using the standard algorithms a less-than operator is required. This is defined in terms of the distance property, which provides a natural ordering for multipe Object intersections for a single Ray.

Parameters

ri	The RayIntersection to compare to `this`

Returns: true if this.distance is less than ri.distance, false otherwise.
