Class DirectionalAmbientLight

java.lang.Object
  threeD.raytracer.lighting.AmbientLight
      threeD.raytracer.lighting.DirectionalAmbientLight

All Implemented Interfaces:

Light

public class DirectionalAmbientLight

extends AmbientLight

A DirectionAmbientLight object represents an ambient light source that always comes from a particular direction. The direction is a vector that represents the direction from which the light enters the scene. By default the light comes from the top, parallel to the yz plane.

Constructor Summary

DirectionalAmbientLight()
Constructs a DirectionalAmbientLight object with the default direction, intensity, and color.

DirectionalAmbientLight(double intensity, RGB color, Vector direction)
Constructs a DirectionalAmbientLight object with the direction, intensity, and color represented by the specified values.

DirectionalAmbientLight(Vector direction)
Constructs a DirectionalAmbientLight object with default intensity and color and the direction represented by the specified Vector object.

Method Summary

Vector	getDirection() Returns the direction of this DirectionalAmbientLight object as a Vector object.
void	setDirection(Vector direction) Sets the direction of this DirectionalAmbientLight object to the direction represented by the specified Vector object.
java.lang.String	toString() Returns "Directional Ambient Light".
