Module raytracer

Package de.grogra.ray.antialiasing

Class NoAntialiasing

java.lang.Object

de.grogra.ray.antialiasing.NoAntialiasing

All Implemented Interfaces:

Antialiasing

public class NoAntialiasing
extends Object
implements Antialiasing

Although this class is implemented as antialiasing method it will not perform any aliasing. Contrary it is used if no antialiasing is needed. The method getColorFromFrustum will only return the color of a single ray that is in the middle of the pixel frustum.

Method Details

initialize

public void initialize(RTCamera camera,
 RayProcessor processor)

Description copied from interface: Antialiasing

Initializes the antialiasing method and sets the camera and ray processor object that has to be used.

Specified by:

initialize in interface Antialiasing

Parameters:

camera - sets the camera object that has to be used for the antialiasing class.

processor - sets the ray processor object that has to be used for the antialiasing class.

getColorFromFrustum

public void getColorFromFrustum(double x,
 double y,
 double width,
 double height,
 Color4f color)

Description copied from interface: Antialiasing

This method has to return a color value determined for a given pixel frustum. A pixel frustum is a sub frustum of the view frustum that encloses exactly a special pixel of the image. The pixel frustum is indirectly described by describing the related pixel.

Specified by:

getColorFromFrustum in interface Antialiasing

Parameters:

x - Describes the relative x position of the top left corner of the pixel. It can range from -1 to +1.

y - Describes the relative y position of the top left corner of the pixel. It can range from -1 to +1.

width - Describes the relative width of the of the pixel. It can range from 0 to +2.

height - Describes the relative height of the of the pixel. It can range from 0 to +2.

color - The determined color for the pixel frustum will be saved in this parameter. So this parameter will be changed!
