Method Summary

void	getColorFromFrustum(double x, double y, double width, double height, Color4f color) This method has to return a color value determined for a given pixel frustum.
void	initialize(RTCamera camera, RayProcessor processor) Initializes the antialiasing method and sets the camera and ray processor object that has to be used.

Method Detail

getColorFromFrustum

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

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.

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!

initialize

void initialize(RTCamera camera,
                RayProcessor processor)

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

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.
