Field Detail

xy

private Point2D xy

Center of the pixel.

width

private double width

Width of the pixel.

height

private double height

Height of the pixel.

split

private int split

Current splitting level.

Constructor Detail

Aperture.Pixel

private Aperture.Pixel(Point2D center,
                       double w,
                       double h,
                       int level)

Constructs a new pixel.

Method Detail

getSplitLevel

private int getSplitLevel()

Returns the split level of this pixel.

split

private Aperture.Pixel[] split()

Spilts this pixel into sub-pixels. In principle, any splitting is possible, but the easiest is to split the parent, i.e. this, into four equally-sized subpixels, each with half the width and height.
