getRadiance
public Color getRadiance(ShadingState state)
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.
- getRadiance in interface Shader
state
- current render state
- color emitted or reflected by the shader
scatterPhoton
public void scatterPhoton(ShadingState state,
Color power)
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.

state
- current statepower
- power of the incoming photon.
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.

if the update is succesfull,
false
otherwise
