Functions

func Distance

func Distance(a, b [2]float64) float64

Distance returns the Euclidean distance between two points.

func DistanceSquared

func DistanceSquared(a, b [2]float64) float64

DistanceSquared returns the square of the Euclidean distance between two points.

Types

type BoundingBox

type BoundingBox struct {
	From, To [2]float64
}

A BoundingBox is an axis-aligned bounding box.

func (*BoundingBox) Contains

func (bb *BoundingBox) Contains(p [2]float64) bool

Contains returns true if the point is in the bounding box.
