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 PhongShader

Parameters:

pl - list of parameters to read from

api - 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 interface Shader

Overrides:

getRadiance in class PhongShader

Parameters:

state - current render state

Returns:

color emitted or reflected by the shader

getOpacity

public Color getOpacity(ShadingState state)

Specified by:

getOpacity in interface AlphaShader
