getPower

public float getPower()
Specified by:
getPower in interface LightSource

getRadiance

public Color getRadiance(ShadingState state)
Specified by:
getRadiance in interface Shader

getSamples

public void getSamples(ShadingState state)
Specified by:

init

public void init(String name,
                 SunflowAPI api)

isVisible

public boolean isVisible(ShadingState state)

scatterPhoton

public void scatterPhoton(ShadingState state,
                          Color power)
Specified by:
scatterPhoton in interface Shader

update

public boolean update(ParameterList pl,
                      SunflowAPI api)
Update this object given a list of parameters. This method is guarenteed to be called at least once on every object, but it should correctly handle empty parameter lists. This means that the object should be in a valid state from the time it is constructed. This method should also return true or false depending on whether the update was succesfull or not.
Specified by:
update in interface RenderObject
Parameters:
pl - list of parameters to read from
api - reference to the current scene
Returns:
true if the update is succesfull, false otherwise
