All Implemented Interfaces:

IPartProperty

public final class RadiativeProperty
extends Object
implements IPartProperty

This class is a part property for the PATRIUS assembly. It is the radiative property of a part. Three optical coefficients are defined in the visible domain (for absorption, specular reflection and diffuse reflection).
