Functions

func Decode

func Decode(h int, scale int) image.Point

Decode returns the point corresponding to a given position along a Hilbert curve of particular size.

func Encode

func Encode(pt image.Point, scale int) int

Encode returns the linear index of a point along a Hilbert curve for a given scale.

Types

type Scale

type Scale int

Scale is the width and height of a Hilbert space-filling curve. The scale must be a power of two.

func (Scale) Decode

func (scale Scale) Decode(hi int) image.Point

Decode returns the point at the given offset of a Hilbert curve with this scale.

func (Scale) Encode

func (scale Scale) Encode(pt image.Point) int

Encode returns the linear index of a point along a Hilbert curve with this scale.
