update
public boolean update(ParameterList pl, SunflowAPI api)
Description copied from interface:RenderObject
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 interfaceRenderObject
- Parameters:
pl
- list of parameters to read fromapi
- reference to the current scene- Returns:
true
if the update is succesfull,false
otherwise

getRadiance
public Color getRadiance(ShadingState state)
Description copied from interface:Shader
Gets the radiance for a specified rendering state. When this method is called, you can assume that a hit has been registered in the state and that the hit surface information has been computed.- Specified by:
getRadiance
in interfaceShader
- Parameters:
state
- current render state- Returns:
- color emitted or reflected by the shader
-
scatterPhoton
public void scatterPhoton(ShadingState state, Color power)
Description copied from interface:Shader
Scatter a photon with the specied power. Incoming photon direction is specified by the ray attached to the current render state. This method can safely do nothing if photon scattering is not supported or relevant for the shader type.- Specified by:
scatterPhoton
in interfaceShader
- Parameters:
state
- current statepower
- power of the incoming photon.
