public class LightRay

extends Ray

A class to represent rays that originate from a point and head for a light source. The LightRay class extends the Ray class with two fields:

• the light intensity corresponding to the illumination of the point by the light source.
• the distance between the point and the light source.

Field Summary

double	distance The distance between the ray's origin and the light source.
RGB	light The light intensity of the light ray.

Constructor Detail

LightRay

public LightRay(Point3D origin,
                Vector3D direction,
                RGB light,
                double distance)

Creates a LightRay object initialized with the specified origin, direction, light intensity and distance.

Parameters:

origin - the origin of the newly constructed LightRay.

direction - the direction of the newly constructed LightRay.

light - the light intensity of the newly constructed LightRay.

distance - the distance between the ray's origin and the light source it heads for.

LightRay

public LightRay(Point3D origin,
                Point3D destination,
                RGB light)

Creates a LightRay object initialized with the specified origin, destination and light intensity. The destination should be the location of the light source. The direction and distance of the newly constructed LightRay are computed from this location.

Parameters:

origin - the origin of the newly constructed LightRay.

destination - the location of the light source.

light - the light intensity of the newly constructed LightRay.
