A shader represents a particular light-surface interaction.
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.
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.
