Package de.grogra.ray2.antialiasing

Class NoAntialiasing

java.lang.Object

de.grogra.ray2.tracing.ProcessorBase

de.grogra.ray2.antialiasing.NoAntialiasing

All Implemented Interfaces:

Antialiasing, Cloneable

Direct Known Subclasses:

MetropolisAntiAliasing, StochasticSupersampling

public class NoAntialiasing
extends ProcessorBase
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 getColorOfRectangle will only return the color of a single ray that is located at the center of the rectangle.

Method Details

initLocals

protected void initLocals()

Overrides:

initLocals in class ProcessorBase

dup

public Antialiasing dup(Scene scene)

Description copied from interface: Antialiasing

Returns a clone of this Antialiasing. All constant variables are copied shallowly, state variables are newly created and copied where necessary.

Specified by:

dup in interface Antialiasing

Parameters:

scene - duplicate of scene

Returns:

clone of this antialiasing

initialize

public void initialize(PixelwiseRenderer renderer,
 Scene scene)

Description copied from interface: Antialiasing

Initializes the antialiasing method using the data available through the renderer.

Specified by:

initialize in interface Antialiasing

Parameters:

renderer - the renderer which provides the needed information

scene - the scene which is rendered

getColorOfRectangle

public void getColorOfRectangle(double x,
 double y,
 double width,
 double height,
 Color4f color,
 Random random)

Description copied from interface: Antialiasing

This method has to return a color value determined for a given rectangular region on the image plane. The coordinates are understood as uv coordinates for the Sensor which represents the camera.

Specified by:

getColorOfRectangle in interface Antialiasing

Parameters:

x - Describes the x position of the lower left corner of the rectangle.

y - Describes the y position of the lower left corner of the rectangle.

width - width of the rectangle

height - height of the of the rectangle

color - The determined color of the rectangle will be stored in this parameter.

random - pseudorandom generator

setPixelXY

public void setPixelXY(float x,
 float y)

Specified by:

setPixelXY in interface Antialiasing

appendStatisticsImpl

protected void appendStatisticsImpl(StringBuffer stats)

Specified by:

appendStatisticsImpl in class ProcessorBase
