        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.
        Specified by:
        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

      • getRay

        public Ray getRay​(float x,
                  float y,
                  int imageWidth,
                  int imageHeight,
                  double lensX,
                  double lensY,
                  double time)
        Description copied from interface: CameraLens
        Create a new rayto be cast through pixel (x,y) on the image plane. Two sampling parameters are provided for lens sampling. They are guarenteed to be in the interval [0,1). They can be used to perturb the position of the source of the ray on the lens of the camera for DOF effects. A third sampling parameter is provided for motion blur effects. Note that the Camera class already handles camera movement motion blur. Rays should be generated in camera space - that is, with the eye at the origin, looking down the -Z axis, with +Y pointing up.
        Specified by:
        getRay in interface CameraLens
        Parameters:
        x - x coordinate of the (sub)pixel
        y - y coordinate of the (sub)pixel
        imageWidth - image width in pixels
        imageHeight - image height in pixels
        lensX - x lens sampling parameter
        lensY - y lens sampling parameter
        time - time sampling parameter
        Returns:
        a new ray passing through the given pixel
