public LightProcessor getLightProcessor()

setRecursionDepth

public void setRecursionDepth(int value)

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

Parameters:

scene - duplicate of scene

Returns:

clone of this ray processor

mergeStatistics

protected void mergeStatistics(ProcessorBase src)

Overrides:

mergeStatistics in class ProcessorBase

initLocals

protected void initLocals()

Overrides:

initLocals in class ProcessorBase

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

Parameters:

renderer - the renderer which provides the needed information

scene - the scene which is rendered

initializeBeforeTracing

public void initializeBeforeTracing(Random random)

Description copied from interface: RayProcessor

With this method the processor is initialized with the Randomizer actually before starting the ray tracing.

Specified by:

initializeBeforeTracing in interface RayProcessor

Parameters:

random - pseudorandom generator

getIOR

public double getIOR(Intersection is,
 Spectrum spec)

getColorFromRay

public void getColorFromRay(Line ray,
 Spectrum resp,
 Color4f color,
 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

Parameters:

ray - input - calculate for this ray

resp - responsivity of camera

color - output - the calculated color

random - pseudorandom generator
