        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.

        update in interface RenderObject
        Parameters:
        pl - list of parameters to read from
        api - reference to the current scene
        Returns:
        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
