Types

type HSVColor

type HSVColor struct {
	H    uint16
	S, V uint8
}

HSVColor defines a color in the Hue-Saturation-Value scheme. Hue is a value [0 - 360) specifying the color Saturation is a value [0 - 255] specifying the strength of the color Value is a value [0 - 255] specifying the brightness of the color

func (HSVColor) RGBA

func (h HSVColor) RGBA() (r, g, b, a uint32)

type HexPlane

type HexPlane struct {
	Values []HexPoint
	Origin HexPoint
	Size   int
}

func NewHexBoard

func NewHexBoard(qnt int) *HexPlane

type HexPoint

type HexPoint [3]float64 // Q R S

func Cube_round

func Cube_round(hex HexPoint) HexPoint

func Pixel_to_flat_hex

func Pixel_to_flat_hex(p Point2D, size float64) HexPoint

func Pixel_to_pointy_hex

func Pixel_to_pointy_hex(p Point2D, size float64) HexPoint

func (*HexPoint) Add

func (h *HexPoint) Add(p HexPoint) HexPoint

func (HexPoint) Q

func (h HexPoint) Q() float64

func (HexPoint) R

func (h HexPoint) R() float64

func (HexPoint) S

func (*LineSquare) At

func (ln *LineSquare) At(x int, y int) color.Color

At returns the color of the pixel at (x, y). At(Bounds().Min.X, Bounds().Min.Y) returns the upper-left pixel of the grid. At(Bounds().Max.X-1, Bounds().Max.Y-1) returns the lower-right one.

func (*LineSquare) Bounds
