true if the update is succesfull, false otherwise

modify

public void modify(ShadingState state)

Description copied from interface: Modifier

Modify the shading state for the point to be shaded.

Specified by:

modify in interface Modifier

Parameters:

state - shading state to modify

f

double f(double x,
         double y,
