Method Details

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 RayProcessorBase

Parameters:

scene - duplicate of scene

Returns:

clone of this ray processor

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 PathTracer

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

Overrides:

initializeBeforeTracing in class RayProcessorBase

Parameters:

random - pseudorandom generator

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

Overrides:

getColorFromRay in class RayProcessorBase

Parameters:

ray - input - calculate for this ray

resp - responsivity of camera

color - output - the calculated color

random - pseudorandom generator

chooseBestPathCombination

public void chooseBestPathCombination(int s,
 int t,
 int lightId,
 Tuple3d combWeight)

appendStatisticsImpl

protected void appendStatisticsImpl(StringBuffer stats)

Overrides:

appendStatisticsImpl in class PathTracer
