Description copied from interface: Shader

Returns an RGB object that represents the shaded color calculated using the values of the specified ShaderParameters object.

Specified by:

shade in interface Shader

Returns:

The sum of the values given by the shade method for each Shader object stored by this ShaderSet object.

evaluate

public RGB evaluate(Object[] args)

Description copied from interface: ColorProducer

Produces a color using the specified arguments.

Specified by:

evaluate in interface ColorProducer

Parameters:

args - Arguments.

Returns:

this.shade(args[0]).

Throws:

IllegalArgumentException - If args[0] is not a ShaderParameters object.
