Radiosity

public Radiosity()

Creates a new Radiosity Processor.

Method Details

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

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 RayProcessorBase

Parameters:

renderer - the renderer which provides the needed information

scene - the scene which is rendered

appendStatisticsImpl

protected void appendStatisticsImpl(StringBuffer stats)

Specified by:

appendStatisticsImpl in class ProcessorBase
