Method Details

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

setRandom

public void setRandom(Random random)

setMaxDepth

public void setMaxDepth(int maxDepth)

Defines the maximum depth of recursion, where maxDepth is the index of the last path vertex

Parameters:

maxDepth -

set2LightPathTracing

public void set2LightPathTracing(boolean isLightRay)

Defines if this tracing is about light ray tracing or importance ray tracing

Parameters:

isLightRay -

traceLine

public PathValues traceLine(int maxDepth,
 PathValues pathValues,
 Line startLine,
 Spectrum initialWeight,
 int sourceID,
 boolean isLightRay,
 Random random)

This function traces a Line(=ray) throug the scene starting at the first path vertex (index =0)

Parameters:

maxDepth - - the maximum path depth (=the index of the last path vertex)

pathValues - - In this pathvalue-instance the results of the tracing will be stored

startLine - - the inital line, which has to be traced further

initialWeight - - the weight of the initial line

sourceID - - the id of the line source (light or camera)

isLightRay - - the boolean for checking, wether this is line is a light ray or importance ray

random - - the randomizer

Returns:

the path result

getPathValues

setCondition

public void setCondition(ConditionObject cond)

traceSubPath

 int startVertex,
 int newVertexCount,
 boolean isLightRay,
 Vector3d direction)

setSafeMemoryMode

public void setSafeMemoryMode(MemoryHelper helper)

getAbbortCode

public int getAbbortCode()
