Detailed Description

This class defines a composite material of two materials that are combined based on a noise function. The result of the noise function is used to base the return value of each attribute on a linear, weighted average of the two materials.

Member Function Documentation

double NoiseMaterial::choose_material ( const Point3D & intersection_point ) const [protected]

Calculate how much of first material contributes to overall material. This is a double ranging from 0.0 to 1.0. The amount of the second material to use is (1.0 - choose_material() )

double NoiseMaterial::get_refraction_index ( const Point3D & intersesction_point ) const [virtual]

Get the refraction index at the point. This may produce some bizarre images if the refraction indexes vary among the materials. It will certainly be incorrect for a noise material as varying refraction within the object will not be honored. Only the location on the surface will be considered.
