Constructor Summary

Scene()
Constructs a Scene object with a default Camera object and no Light or Surface objects.

Scene(Camera camera, Light[] lights, Surface[] surfaces)
Constructs a Scene object with the specified Camera object, Light array, and Surface array.

Scene(Surface[] surfaces)
Constructs a Scene object with a default Camera object, no Light objects, and the surfaces represented by the specified Surface array.

Method Summary

void	addLight(Light light) Adds the specified Light object to this Scene object.
void	addSurface(Surface surface) Adds the specified Surface object to this Scene object.
Camera	getCamera() Returns the Camera object stored by this Scene object.
Light	getLight(int index) Returns the Surface object stored by this Scene object at the specified index.
Light[]	getLights() Returns the Light objects stored by this Scene object as a Light array.
Surface	getSurface(int index) Returns the Surface object stored by this Scene object at the specified index.
Surface[]	getSurfaces() Returns the Surface objects stored by this Scene object as a Surface array.
void	removeLight(int index) Removes the Light object stored at the specified index from this Scene object.
void	removeSurface(int index) Removes the Surface object stored at the specified index from this Scene object.
void	setCamera(Camera camera) Sets the camera of this Scene object to the camera represented by the specified Camera object.
void	setLights(Light[] lights) Replaces all of the lights of this Scene object with those represented by the specified Light array.
