Types

type Rect

type Rect struct {
	Center, Size V
}

func (*Rect) Golden

func (r *Rect) Golden(c V, a float64)

Golden rectangle with side y. y/x = (x + y)/y = math.Phi

func (*Rect) IsInside

func (r *Rect) IsInside(t V) bool

func (*Rect) Ratio

func (t *Rect) Ratio(c V, y, r float64)

func (*Rect) Square

func (r *Rect) Square(c V, y float64)
