Method Detail

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 interface RenderObject
Overrides:
update in class TriangleMesh
Parameters:
pl - list of parameters to read from
api - reference to the current scene
Returns:
true if the update is succesfull, false otherwise

init

public void init(java.lang.String name,
                 SunflowAPI api)

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 interface Shader
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 interface Shader
Parameters:
state - current state
power - power of the incoming photon.
