Method Detail

appendStatisticsImpl

protected void appendStatisticsImpl(java.lang.StringBuffer stats)
Overrides:
appendStatisticsImpl in class PathTracer

chooseBestPathCombination

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

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

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 RayProcessorBase
Parameters:
ray - input - calculate for this ray
resp - responsivity of camera
color - output - the calculated color
random - pseudorandom generator

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(java.util.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
