Method Detail

appendStatisticsImpl

protected void appendStatisticsImpl(java.lang.StringBuffer stats)

Overrides:

appendStatisticsImpl in class BiDirectionalProcessor

dup

public RayProcessor dup(Scene scene)

Description copied from interface: RayProcessor

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

Specified by:

dup in interface RayProcessor

Overrides:

dup in class BiDirectionalProcessor

Parameters:

scene - duplicate of scene

Returns:

clone of this ray processor

getColorFromRay

public void getColorFromRay(Line ray,
                            Spectrum resp,
                            Color4f color,
                            java.util.Random random)

Description copied from interface: RayProcessor

The main method of a ray processor. This method computes a color for the specified ray. color.w contains the alpha value for the ray, the other components are premultiplied with this alpha value.

Specified by:

getColorFromRay in interface RayProcessor

Overrides:

getColorFromRay in class BiDirectionalProcessor

Parameters:

ray - input - calculate for this ray

resp - responsivity of camera

color - output - the calculated color

random - pseudorandom generator

getMutatedPixels

public int getMutatedPixels()

getResult

public PixelwiseRenderer.Result getResult()

initialize

public void initialize(PixelwiseRenderer renderer,
                       Scene scene)

Description copied from interface: RayProcessor

With this method the processor is initialized with the scene and other information of a PixelwiseRenderer.

Specified by:

initialize in interface RayProcessor

Overrides:

initialize in class BiDirectionalProcessor

Parameters:

renderer - the renderer which provides the needed information

scene - the scene which is rendered

initializeLoop

public void initializeLoop(float brightness,
                           int imageWidth,
                           int imageHeight,
                           int mutatedPixPerProc,
                           MetropolisRenderer.MetropolisResult result,
                           int procId)

mergeWithRenderer

public void mergeWithRenderer()

pathChanged

public void pathChanged()

resetAll

public void resetAll()

setMinMaxPathLength

public void setMinMaxPathLength(int testLength)
